please don't hurt yourself, it is the worst thing anyone can do to themselves. you're only 23, you have your whole life ahead of you! and a disability can make life tough, but life is still worth living, and dreams can come true! get a pen and paper and write down your hopes and dreams, then write what you need to do to acomplish them! i am 19 years old, will be 20 on 4th of july, and i moved out of my parents house when i was 15. i had my own appartment and was going to school every day, along with exams, schoolwork, keeping the house clean, paying the bills, buying my groceries, visiting my grandma (and grandad when he was in hospital). i worked my ass off, kept my house clean, and got top grades for my exams. i stayed on for an extra year to study languages, then i got a job in a factory for 3 months and saved up all my money, and now i am living in brazil teaching english
it hasn't been easy, infact life is hard as fu*k sometimes, but i would never throw such a precious gift away. you need to have a goal, and the drive to accomplish it. set yourself a goal every day, even if it's something simple, like walking to the shops, and you will feel better. also, go to the doctors and tell him how you're feeling. and the best advice of all? get yourself a puppy
people with pets are less likely to be depressed, they make you more active and get you out the house, and you will have someone to stay alive for! i really hope you feel better about yourself soon
