i can relate to some of the feelings you describe - I put off going to the gp for a long time because I was "just tired and stressed". 3 months ago I finally went and doc put me on meds for anxiety and depression.
I am great at being cheery, so much that when I tried to confide in a friend about my depression she simply didn't believe me.
But I am tired, so tired. Sometimes the thought of having to get up in the morning and be a person all over again is a physical weight, sometimes I feel paniced at the thought of going to bed bcause it means waking up and a new day starting.
Sometimes I feel like I am not real. I am floating through life not connecting with it and everything is just an act. Like none of it matters.
I have intrusive thoughts - I don't hear voices but I do constantly think negative things and I can't stop them. You did that wrong. You pissed her off. You fucked it up. You've failed the kids. Your husband thinks you are ugly. Look how fat you've got. My self esteem is at an all time low, and yet I am so good at dancing the dance of the confident and acting all "look how awesome I am!"
I struggle to enjoy things I used to love. Because I see the negative in everything. I went to a theme park recently and I love roller coasters. But on each one I was like "wahoooo this is awesome! But wait, if it goes wrong, I'll die. I'm going to die. My brain feels weird, am I having a stroke? I can't breathe" etc etc. Really bloody irritating.
I also have a lot of issues around food.
Im on meds and having therapy. I don't know yet whether they are helping.
Go and see your GP. I put it off for too long and I am finally in the system and on my way to getting back to some kind of normality, you can too xxx
Feel free to PM me if it will help xx
