Hey man. First and foremost, I'm very sorry that you've been through so much pain.
You said you don't see any future plan. Have you really exhausted your options? How long have you felt this way? I'm not asking to belittle how you feel, I'm asking because I care. Hopefully this isn't something you've only recently just started experiencing (say, perhaps a month or 2 ago...).
We're all here to talk to you and support you in the meantime. Regardless if you do or don't go through with your plan. If your mind is made up 100%, why not chat with us and allow us to be there for you?
Best wishes in the meantime.
