Do I tell my GP

[Sunmoonearth]

I’ve never told anyone or spoken directly to anyone about it. I have an eating disorder. It has been going on for more than 30 years.
It has been very noticeable at times (very very underweight) and on the few occasions it has been mentioned I’ve denied it.
It currently isn’t very noticeable. I’m not underweight (feel huge and fat) but I’m not eating much and am deficient in almost everything (had blood test recently).
I’ve been in denial for a very long time.
Thing is, because I don’t look particularly unwell, I expect I won’t be taken seriously and I doubt I would get a referral.
Even if I did, they probably can’t help me as it has gone on forever.
So do I tell someone? Do I speak to my GP or will that be a waste of time?

Definitely speak to your GP. Tell them how long it's being going on for. All the best OP 💐

Where do I even begin? And after such a long time how could I possibly expect that they could even help?

Maybe you could write it down, like you have here, and give it to your GP. If you don't feel able to explain verbally.

Perhaps I could. You can read lots of news about very unwell people who don't get offered treatment so how can I expect to when I'm not currently as unwell as I have been?
What I don't want to do is have all the stress and embarrassment of telling them and then no one does anything or they can't refer or help (or won't)

The doctor probably already knows, and will be glad you are ready to talk about it & are asking for help.

You think so? Will I even be able to receive treatment if I'm not underweight? How do I approach it and what do I say?

Me again.
Would anyone have any advice or experience in how to approach this successfully?
While things are not so bad now, things have been very bad (BMI 12 - 14 for a number of years - currently 21), I don't think there is any improvement in how I feel. And things are going backwards again.
I'm worried I won't have the energy to see it all through.
Feel so low atm.
Any advice or experience is appreciated.

Make an appointment to see your doctor. Try to write down some key points to share. Regardless of your current BMI/weight/etc., they should take it seriously and help you in some way.

Thank you Cakeandchampagne. I will try to work up some courage.
