<human>: Can you provide a brief overview of the text?

I've always been anti-social at worst and an introvert at best. Add to that I can be extremely irritable/rude at times. I've always managed to make friends/boyfriends at school/collage/wherever I went, but thats only to pretend to be normal. I've never been interested to remain in contact with them afterwards and the only ones still in contact are the ones who won't let go despite zero effort from my part.

Somewhat same for family; I love my siblings, my parents but I can't be bothered to give them quality time..or any time infact. After chewing out my bro verbally last night, he's finally given up and said he does not want to be in contact with me anymore and if i keep to my behavior everyone's gonna leave me eventually. This is a bit of a surprise, not that I haven't foreseen it. How can I make myself care more? Why is that I'm so apathetic towards human relations. I don't get it.
<bot>: I put zero effort in my relations. Perfectly happy with being alone but this is no good in long terms thinking practically so how can I make myself care?
