Never expect too much

One big lesson I've learned recently from problems with friends is that you should never expect so much from them that it's overbearing and almost needy.
After all, they've done enough by being there for you and being your friend in the first place, and sometimes people just need a break and time for themselves or other people.
Part of growing up is learning what certain people bring to you and teach you.
To be specific, I recently overreacted when a close friend with whom I hadn't hung out with in a while had previously-made plans when I asked if he wanted to hang out.
Thinking back on it, I just want to laugh, because even though I missed him a lot and just really wanted to spend time with him, I was being selfish by thinking only of myself in the situation. I've always had a problem of feeling like the victim in a situation or like everyone is out to get me. The reality of it is that I am just paranoid and never see things from the other side. He couldn't help that he had plans! That's just one small example.
Lesson learned:
We need to understand that friends will always be there for you when things get ugly and for good times and laughs, but we can't be overbearing and greedy with their time and friendship. Sometimes we all need our space...
