It used to be my mother, because I thought she would be pretty upset, but not anymore. I think in the long run it will be a massive relief more than anything as she will no longer have to deal with me.
I think I'm a good candidate to CTB as far as practical reasons go. My only family is two siblings and my mother, I either don't know or am estranged from everyone else. My siblings and I would not have a relationship at all if it were not for my mother. If I outlived her we would definitely never have one again. I am 30, never had children, so nobody I am leaving behind that I am solely responsible for. My partner is tired of me and doesn't want a future with me anyway, so they will be ok (and like my mother, probably super relieved in the end because they no longer have to deal with me). I have a cat, but he loves and adores my family and vice versa, he will be well taken care of for the rest of his life and I know that with certainty. I have isolated myself over the years so I don't really have any friends who I have to worry about. I am not a person of great importance nor have I done anything good or special, so all trains will run on time regardless of whether I am alive or not.
A lot of this contributes to depressing me, but it's also a relief to know that I will be able to go without doing any real damage to anyone or anything. I take comfort in that
