Awww bless you!
your post has brought a tear to my eye.
Not sure if you've thought of this, but how about (seeing as your good with art) card making?
Have you looked into what benefits you may be entitled to?
How about seeking work in a local animal shelter? Whilst you will have to face people there, most of your 'clients' will be the furry variety, and I've often found them to be far more pleasant than most folk!!!
However, I really think the main issue is your lack of confidence, your only 32 and if this can be addressed your outlook and future will be so much more brighter. Have you thought of discussing this with your GP?
Most of all, I wish you good luck whatever you decide to do.
Boo
