I'm 37 and feeling totally washed up and miserable. I just can't unfuck my life.
My teens and twenties were taken up with failing at life with a serious autoimmune disease, depression, an eating disorder, a parent dying of cancer, a suicide attempt, worsening disabilities, and then an ADD diagnosis.
I'm not depressed anymore and miraculously sort of physically ok, although have some serious physical limitations. But everything just feels too late for me now.
I have two mediocre degrees, a BA and a MSc so not thinking of more studying. I was really good at a couple of things when I was at school, which I guess my confidence and self esteem were built upon. But now it's all drained away.
Technically there is nothing stopping me picking up these things again - but I just seem too ashamed of myself? I have completely lost faith that I have anything of value to add. I feel all my ideas are complete utter shite and the world will ridicule and pity me if I try to participate now.
I feel like I can't cope with more failure, more sneering, more confirmation that I'm simply a totally shit worthless person in the eyes of the world. So I just do nothing 
How do I unfuck my mental approach here?
