I'm not sure how serious you mean that, but since you're posting it here, probably very. I just want to tell you, that even though it's hard to understand your situation, when you're not in it, please don't end your life because of something like this. It's a scratch that needs fixing, first of all, for sex, then it's of course the loneliness of not having someone who cares. But if you end your life because of this, I always feel like then the people who don't understand or who are hostile towards people being different and living unconventional - yes, sometimes sadder - lives win. I mean then it's just them, these people who don't understand deep sadness or loneliness, feelings probably you are feeling, and their lives are probably shit too, you know. They live without knowing a big part of life, and that's these deep feelings of sadness etc. And I think you shouldn't give away your place in life for another one who has no clue or who can't process that life is not happygolucky for anyone. We need different people living different lives and should always try to better ourselves and with that the world around us. Maybe you can work towards a world where people like you are more successful when it comes to relationships, maybe life in general? But don't just escape and leave the field, because then people will not know that there are these harder lives, with harder fates being dealt to them. And that's a loss, it's always a loss!
I hope you change your mind, because this is really you deciding if you want to do that. Life has so many other nice and beautiful things besides women and special others. It's one part that would be nice, but then again, no one has the whole cake in life, and maybe one has to get used to this.
Stay hopeful if you can, and try to live on. It would be a real shame if you wouldn't. Even in this forum your point of view has been totally different and probably enlightened many, who didn't know people like you exist and how you think etc. can have a big influence on people in real life too.
Hope this doesn't sound too corny but really I feel sad reading things like that, and I think you belong to a group of people who are constantly being labelled as madmen etc. and it's unfair, in my opinion. But that's why there's a big need for people like you.
