Words cannot express how bad I feel right now, only the promise to my psycoligust is keeping me from committing suicide 
Don't see any point in carrying on, I know I can get a little better but it's extremely unlikely I will ever be anything like I used to be. If I can never be my self again what's the point
Cornish I'm so sorry you feel like this. This is one of the most difficult times you have ever had to deal with and you have been through an awful lot. You are feeling so desperate and sad and I sense you are in total dispair.
You are a very courageous person. You are still here because of your courageousness, stubbornness and honour to your promise to your psychologist who you respect a lot. I am very glad you made that promise and are still here today. You are very important to your family, friends, us and me. Your mum is desperately concerned for you and somtimes doesn't show her feelings very well because of fear but she loves you very dearly and would be desperately sad if you ended your life. As would the rest of your family and of course us.
Your memories of yourself before your accident are painful and make you draw comparrisons between yourself then and yourself now. From what you have said, it sounds like the possibility of you returning to your old self is unlikely but not impossible. Maybe that is not the goal though. You can transform through this, shape and change. It has affected you and you have learned and grown so much through this experience. You have been through too much &$%+ over this illness to just give it the satisfaction of claiming you now. Please see Cornish, that you can come out the other side of this what ever that may mean. Perhaps the aim now is not to return, but to get out.
You have been through such traumatic, torturous times with such courage and strength, that I can imagine you would be BRILLIANT at developing a career or even voluteer work at helping others come to terms with their similar experiences. I believe that might be the point in carrying on. You are an inspiration. An amazing man. some one to look up to and admire. No one I know is coping with what you are coping with and you have shown many many people your tyranny over your illnesses. We have such respect for you and I am humbled in your presence.
