Even my social life is stressful. My friends change more often than I would like. Although I have had two friends for a year, I find that my bigger social circle changes because of back-stabbing and manipulation. I watch myself do the same things to others sometimes. Relationships seem perfect one day and then with no warning the other person stops calling.
Friends also sabotage relationships by spreading gossip or getting involved.
I wish people could be honest when they want to break up. I'm trying to be a better person, but it's hard. Writing about yourself brings the abstractions of the original piece down to a nuts and bolts level that we can all understand. Keep fighting for yourself, and I'm sure you'll make it.
