I'm generally happy in day to day life but I'm quite isolated, no friends or partner, few close relatives, I have an unskilled job with no prospects and it's unlikely I'm ever going to be able to afford to have children... I feel quite pointless.
I've looked into doing some volunteering but it's all charity shops (I have more than enough shop work in my job) and roles requiring people skills, which I don't have. I can't even give blood because I'm short and small so I don't weigh enough.
Any suggestions of little things that I could do that might give me a sort of sense of purpose?
