So I'm a little weird, what might it be?

Hi guys, I am using a throwaway for this because it's personal.

This is may be a medical thing, so before you slag me off for asking on the internet, this isn't something (yet) that is causing me any kind of medical concern, I will see a doctor as and when I feel I need to.

So...here goes.

I have a lot of tics, facial ones and other ones. I know the facial ones are more obvious so I manage to control the situation by using the less visible ones.

The facial tics are random, mainly involving my lips and eyebrows. The others I have involve my fingers, certain muscles I twitch intentionally etc, plus I do certain things in certain patterns and they have to be in those patterns or it just feels wrong.

I have this feeling about life that I have to do things in the quickest way, like parking the car, I feel really strange parking the car unless it's in the nearest possible slot to where I am going.

The worst thing for me that is starting to piss me off is when I go into a situation and the situation changes, I find myself getting angry because something doesn't quite go the way I expect it. A good example is going to McDonalds, asking for a shake and them not having one, it completely changes me, because I can't handle the unknown if I have planned things out.

I have no imagination whatsoever, seriously I don't, I can't imagine things and have a habit of just saying things that freak people out because I can't picture things in my head.

I've been like this for years and have been able to live with it and hide it pretty well, but in the past few months it's been getting worse, especially the tics and I've been wondering what might be causing it.
