I don't know how to interact

I'm lost, oh boy am I lost. I have a linear understanding of interaction with people, vertical for the most part that falls out.  Everyone I have ever met has either progressed far or not at all, in terms of my interaction with them.  I know few people that I would say I hang out with, and a very very select few I will see time to time.

From my school I think I saw 10 people over the summer at most. So many people that I knew that I have virtually no ties with at all.  What a fun time I've had with post central debate, but I wonder if I am casted strictly to an aside, a late comer of sorts? I fell so bad for being a drifter in groups.  Makes me feel like such a prick.  I traveled a very clear route in my head retreating back to previous friends when things go sour. 

I think in a way I ran to someone broken down with I really need friends right now.  Its so sad to see myself as this, exposed onto myself.  How do I not form healthy human interactions? Why am I socialized so differently than most people?

I sound swell, try a relationship. Christ, I'm a train wreck.  I have never interacted with anyone normal, only people as screwed up as me.  So now interaction is awkward, I see Jen for debate and BAH that I do not understand.  Fun time! I guess I was laughing at her? I'm perplexed but she doesn't talk to me at all, around other people, but offers to give me a ride? This is backwards? Maybe? I don't know what to do! I don't know how to interact, I have very specific understandings based off previous to build to a spot.  It's like a knot all attached, my understanding of a person.  I toss out a portion it takes it all, and I am left speechless, confused and flabbergasted.

I can barely talk to my family, how did this happen? I have no idea.

But I'm fairly happy.
