I have a finite amount of energy every day. At the moment the overall total amount of energy I have is minimal, so it gets spent on personal hygiene and going to work every day.
Someone else said that their world got smaller - that's the same with me too. Hanging out with friends and family doesn't interest me at all and I don't get any enjoyment from it, so I try to limit it to mandatory occasions to keep the bare minimum contact ticking over. Ceased contact with broader acquaintance group.
After a busy week I can often go Friday evening to Monday morning not talking to anybody and lying in bed (I live on my own), not washing, house a tip.
I have disordered eating and I have put on 6 stone in 2 years which makes me fucking hate myself. I wish people would see it's a cry for help and an invitation to ask me about my mental health, but I have such an iron mask of happiness that maybe people assume I am fine.
I deal with suicidal thoughts quite a lot, especially when I think about a long lonely future (no social life + fat = Reduced likelihood of finding a partner and having a family) - I feel powerless to change it though when all I can do is take one day at a time.
I got up the courage to go to the GP once, with a written statement about how I felt so that I could disassociate myself from the moment and actually express myself coherently. He was dismissive and said my dad feelings were probably due to a poor relationship ending a couple of years previously (I know - wtf?!) That kind of crushed my confidence in reaching out for professional help. It's down to me really. Just plodding on.
