Over the last few months I've been trying to learn martial arts as my main hobby. The problem is, I really struggle with performing the techniques shown to me. I constantly need correcting and just constantly make the same mistakes. I also really struggle to mirror what the instructors want me to do. I'm not sure whether I have some kind of learning difficulties that I've never been diagnosed for or if it's because I'm really nervous, or both. It's humiliating to be so awful to the point where instructors clearly feel sorry for me.

My martial art experience so far is:

I did wing chun with one school for a month (twice a week, two hours a class). Everyone was very advanced, and I just consistently messed up almost every technique I was taught. I could see it in the advanced student's face that I was hopeless (and he had a lot of patience). But the thing that made me quit was when we were doing some kicking partner drills and the advanced student was so frustrated at how bad I was that he just went off and did his own thing.

More recently I tried a Japanese jujitsu class. Again, I just couldn't mirror the instructor's warm up movements to the point where the girl behind me felt sorry for me and helped me out (I had only been in the class for ten minutes). Then the instructor tried to teach me break falls. I mentally couldn't bring myself to fall like he was showing me. I really tried, but I just couldn't. Then when he tried to teach me easier variations, I would fall, but incorrectly, every single time. Of course, after a while the instructor felt sorry for me and started trying to make me feel better while trying to get me to do any technique. He showed me the hip throw, which I struggled to remember all the steps, then when I did them he constantly told me my foot placement was wrong and I just kept making the same mistakes.
 
*What can I do to overcome this?*

I've got a muay thai class on Monday and I fear it's going to be the same deal. I intend to continue the jujitsu as it looks like it is will be really useful with muay Thai, plus the people were nice and patient.
