I'm really confused about friendship.
Some of my friends from school aren't great people anymore. I know I'll cut them out of my life now that I'm graduating. Though those I do care about, I'm afraid I won't be friends with them any longer since we won't have anything to talk about anymore. I can't see myself talking to them anymore.
Some of my older friends, whenever they want to hang out I'm sick or busy and it makes me look uninterested, we don't even talk much. Today I even missed the birthday of someone I've been friends with for 14 years.
And online friends. I'm afraid drama will happen and I'll lose them or they'll hate me for some reason.

I don't want friends anymore. This stuff is rough. Not to sound emo, but being alone sounds easiest, right? I just wanted to hear another opinion on this. I don't know why I should make friends if I'll just end up losing them or end up being a bad person to them without realizing it.
