Where do I fit in this world?

How does an introvert, somewhat ADD girl who works too slowly, gets distracted easily, has terrible social skills/communication skills, who tends to dislike most people fit in this world?

My contract is ending again. I feel like I'm perpetually worried about where to go next. In trying to understand myself, I have learn that I am disorganized, too idealistic and therefore not very good at putting ideas into concrete results. Hence I'm terrible at writing project proposals as well as making a manuscript. I am terrible at dealing with people. Seems like I don't get along with 90% of whoever I encounter. The 10% I do get along with are probably the most easy going and socially intelligent people in the world, which means they get along with 99.9% of the world's population.

I took up a technical job because I thought I could just hide behind my desk and just churn out good work + make a living out of it. But it turns out I am too inefficient. So far I haven't had a position where I am really good at what I do. Now I don't think I am stupid (low on EQ and Social Intelligence, but not IQ), but I probably aimed too high in terms of the type of job I think I can do.

I still think science is the right type of job for me. Unfortunately the current system does not allow people with my kind personality to stay in the field. Grad schools keep pumping out PhDs, who are eager to work for peanuts for a few years under professors as postdocs. Because of this, there is no reason to keep experienced scientist in your lab, because the salary goes up. Also, because of the funding structure, every job is temporary. I'm at an age where I want to settle down but I have no idea which country will allow me to stay for long term.

In addition, to survive in the research field, every professor is making their lab members work on 5 projects at once. I know the logical thing to do is to focus on one project at a time, but since I spent 6 years working on only one project, right now I have no idea how to juggle 5 at once. I am constantly stressed out, have no time to cook and exercise. This is really a terrible situation.

I really think I could use a retreat, but right now I'm using my vacation to visit family, which is more stressful than relaxing. My mother still doesn't get that I don't like her planning my life. It's her thing to force her offerings (presents, food, money, planning activities) on other people, regardless of whether they want it or not. You might think that, what's wrong with free things? Why would anyone decline free stuff? Well, nothing in life is ever free, even if it's offered by your own mom. Basically she wants you to be her slave if you dare to accept her presents. She would tell everybody how much she has given you. She would expect you to do favors for her at a time that's totally inconvenient for you. Sometimes she offers you something that is more a burden for you than a present. But she still counts it as that you owe her a favour. I'd much rather have my freedom than take her offerings.

Anyways, I need to find myself another job that would not make me want to pull out all my hair and cry about not being able to deliver. And I'm tired of moving around. Question is where should I go next. I'm too busy to do any serious job hunting. Perhaps over Christmas time.
