Imured:
First, read what Anna54 said. I agree.
Second, whether we all like to face it or not, we are ALL alone. That shouldn't bother you, because it's just a reality.
Finally....it's not about anyone else missing you if you were dead. I'm sure they would, but I'm not going to argue. It's about picking yourself up, brushing yourself (your mind in this case) off, and realizing that you are not better or any worse than the rest of us. If you're having trouble dealing with something, why don't you share it with us? We might not be able to help, but you've got over 15 thousand friends here.
I happen to know Anna (not personally), and she's one of the people here (again, there are lots of others...me included) who will listen....maybe try to help, but at least you're not alone. No one is judgemental here (or at least most of the time). It is always far better to figure out what's bothering you, take it (as someone else greyven (not sure I spelled that right) one step at time...or maybe it was someone else...but it's good advice. Most of us have been where you are.....which means a lot of us will be your friends.
Look, maybe it's going to be hard to do, but the holidays are comng up. Take the opportunity to be nice to yourself! I can wish you a happy holiday season (and of course, I do) all I want, and if you don't take some steps to cheer up, it's not going to do a bit of good.
I'm one of the older members of this board (not THAT old), and I've seen a lot, and life has a way of turning out okay if you just sit back (emotionally) and don't let it get to you.
Cheers.
