Your existence is not pointless. You're a strong, witty and intelligent person - who happens to have been dealt a s-hitty hand in the health and family departments. You're very useful around here. Youre blunt, humorous and reflective posts help a lot of us. You're not afraid to tell it like it is, and I certainly appreciate that.
I hope your surgery goes smoothly and it improves your daily living. I'm sorry you feel so alone. I know how hard it is to
open up to people, or, well, how hard it is to even find someone ok enough to want to try and
open up to them! I find most people annoying and offensive. If not speaking with your family is relieving some of your stress/frustration than good on you, if they're emotionally hurting you and offering no support/love than they're not worth your time.
Make sure you let the team at the hospital know that you won't have help at home after you get discharged. Don't want you to get booted out too quickly! Please keep us posted, there are a lot of people on here who will be thinking of you.
