Brick Walls, I can't breath anymore

Here's the story in a nut shell, my circle of people consists of the following group.

1. Someone who'll do anything to get whatever they want in life, even stepping on their closest friends.
2. Someone who thinks they can handle themselves with anything life throws at them, when in fact, they're as vulnerable as a new born cat.
3. Someone who'll get upset about anything that clashes with what they believe.
4. Someone who's had a bad experience and won't let themselves try and let anyone else have a go.

Now, here's how they interact:

A. We have (1) making passes at (2), when failing, tries to turn me against (2).
B. (2) despises (1), and they're right.
C. (1) pulls (3's) leg by indulging in provocative conversations, (3) demands (1's) head in return.
D. (4) is just unsure what they want to do, which makes life difficult to everyone.

Now, here's the usual conversation:

1. Thinks you over-react.
2. Tells you you think too much.
3. Tells you you're far too lenient.
4. Tells you you deserve a better life.


With me in the middle trying to keep everyone happy, and I'm tired of it, I'm pushing 4 walls that are closing in on me.

FFS, why can't I be as happy as everyone else, is this a crime?!!
