To ask you what is wrong with me?

The NHS is rubbish in relation to b12. You can have dire results but the nhs will tell you you’re totally fine. Ask for your results and post them here.

Under-active Thyroid would be my guess,

the range for normal is pathetically led with regards to gps. Say in layman’s terms the range of normal is between 3-8 someone could be Al happy and thriving at 3, and someone else could be on their knees struggling like you are. But because it’s “in range” then they don’t care.

id ask for further thyroid checks.

peri could be part of it, could be a few things together.

Also, sert could also be having an impact. I don’t think this is one issue.

get a new gp this one isn’t doing you any justice.

Docs told me my iron was "normal" but when I actually looked at the ferritin levels they were about 50 which for many women is simply not enough. I had an iron infusion because tablets irritate the stomach and are not as effective. It made a huge difference. I also went back on the pill which is acting like HRT because peri won't show up in bloods usually.

Mine too.
Reaction to vaccination/booster?

Another vote for perimenopause. I know lots of women early 40s and already getting HRT

I have underactive thyroid, it's caused by autoimmune disease and runs in my family. Docs have know for years my levels were dropping but "within range" yes within 0.5 of the bottom! Argued and pushed to be given theraputic dose of thyroxine, I feel like a new woman! Hair and nails regrowing, anxiety almost gone, sleeping at night and sex drive back. I would ask for your actual numbers from bloods not just that they're "normal" or "in range". Good luck.

Ask your GP to recheck your thyroid and your ferritin levels.

Also, sleep apnea should be looked into if you feel like falling asleep anywhere.

Iron, vit D and vit B12 very important.
Should all be in the middle or upper part of their ranges.

I also agree with perimenopause. How old are you op?

I am 44 and have recently started HRT due to similar (but mess severe) symptoms to you. Still early days no no huge differences yet but I’m hoping it helps.

I feel anxious. Low and permanently tired. I am also a single parent to two teenagers and work full time though so I guess a degree of tiredness is to be expected!

Thyroid problems?

Have you had sights of said “normal” blood test results?
Can you have a look at the main ones and see if any are borderline high/low?
Many of our “lab ranges” aren’t actually the functional ranges as when they were established, people with too low/too high values were included making the ranges far from what they should actually be for our bodies to function properly. (This is a bit long to explain, especially since I’m relaying 2nd hand info and I’ve probably done a poor job of it).

For many people these ranges may be ok, but for others even just “borderline” values, which GPs
often ignore, can be causing problems.

I would second and third people asking if you have your actual blood results to look at.
Iron, Vit D, B12 and Folate (which I doubt GP would have checked for) are the obvious culprits and the GP will say "they're fine" or "they're a bit low" but look at the Iron protocol on Facebook for help with ranges and actual dosage needed to increase these - there's not enough in a multi vitamin to address any of these and actually taking different things together can block absorption so that can be an issue too.

And I had to fight to get thyroid meds because it wasn't quite out of range but at the very upper level of what's"normal" with all the symptoms.... so get that number too.

Can you rule out exhaustion?

It could very well be lots of different things. But it could all stem from the not sleeping - it can cause all your other symptoms.

Have you tried sleeping pills? Can you ask your GP for melatonin? Or even just try some antihistamines? Ask GP what you can get to help you sleep. I realise this may be difficult if you have a 2 year old, but is there someone else that can deal with any night waking?

You sound exactly like I felt. I’m 42 and now on HRT, because my GP is great. It’s made a difference.

Side note, if you are anaemic a multi vitamnin won’t cut it. You need iron supplements and b12, and about 4-6 weeks to feel the difference.

Have you got print outs of your bloods or the actual results?
Mine were "fine" but actually weren't

CFS is chronic fatigue syndrome

It actually sounds like chronic anxiety to me which is getting worse as you feel that no one will listen to you and your brain is telling you you must be ill.

i have had anxiety on and off for years and I was absolutely wiped out with it for a period. Felt absolutely shattered every day, my sleep was broken, I had no energy, was breathless and and I was convinced something was wrong with me. Eventually a drug sorted me out and keeps me on a relatively even keel now but I am still prone to bouts of the above From time to time.

I agree with a PP you might want to consider gluten intolerance.
It's definitely worth cutting gluten out for a month to see if it helps. You'd feel a difference after two weeks probably. Also don't be fooled by thinking you can't have an intolerance because of your lack of bowel symptoms etc... plenty of people don't have the 'standard' symptoms.

It causes vitamin deficiency due to the villi in your intestines being damaged znd not absorbing nutrients. Also causes brain fog and extreme fatigue.

Also, make sure you're not drinking tea within an hour of taking your vitamins (or eating). The polyphenols in tea decrease iron absorption by up to 90% so it's really important.

Sounds like menopause, not peri if you haven't had a period for 3 years. Maybe review the oestrogen again; HRT could really help.

Have you had your B12 checked?

Do you have breast implants?

Could you have been bitten by a tick? Some of what you're describing matches Lyme Disease. Otherwise I'd be thinking perimenopause.

Have you got access to your blood test results on the NHS app? If so, I suggest having a look at them. I was shocked to look at mine and find that my ‘satisfactory’ blood test results were absolutely dire and several of them were at the very bottom of the ranges given. Feeling a lot better after supplementing ferritin, B12, folate and vitamin D.
