Accept loneliness

I remember in the heat of an argument an ex girlfriend of mine screaming at me saying “one day you’re going to die sad and alone…” At the time I just thought like “man, what a bitch” and was just pissed off that she would go to such lengths not to prove a point but just hurt my feelings. But now that one thing has kind of haunted me and become pretty much the one thing that I fear. Sometimes it seems like I don’t do well with the other people around me, I don’t keep friendships the way that i feel i ought and I’ve never done so well with relationships (obviously) and it just seems like I always end up back in my own company. Which is not always that bad, just sometimes bad. so i guess the best remedy for anything is just a positive attitude and for those times when I have a little more of myself on my plate than I need I should just relish in it and accept that it’s just part of the way I was built.
