Having had a family member say all this, and been through them wanting to end it al so many timesl, so I am going to be a bit brutal.
I just have a few questions - how are you going to do it, what happens if it goes wrong and you are left incapacitated, and what would you then say to the remains of your family who are left with the problem of coping with you, assuming you can still comunicate?
Perhaps you need to take a little time, think about the things you have to live for, and get yourself some help. The Samaritans are great at listening and there are many other people who will help. If you need to come on here asking what to do, you must be prepared to listen a bit...........
