Too stupid for the A2 driver’s license?

Hey guys I wanted to know what you think of my situation, I’m 18 and started with the A2 driver’s license about 2.5 months ago. I’m driving a Honda CB650R and I just don’t feel comfortable anymore, I’ve fallen over with the motorcycle for the 3 times today!! The first time was in the first driving hour, I only come to the ground with the toes (I’m 1.62m tall) and I wanted to stop my left leg on the ground but I kept it a little too crooked and the Bik e was so hard for me that I just couldn’t hold it. I also made my car driver’s license with the driving instructor and we got along really well, he was then annoyed however and meant the bike he first got new and of the 8 driving students he has just done I am the first one who overturned it. Since I already felt bad, but shortly afterwards he encouraged me again that we can do it all. Then I had a few driving hours at denen also al Les worked well with slalom, dodge etc but braking was always my problem because I just got to shake after the brakes, I just don’t know why I always make sure that my handlebar is straight but I have totally problems with it until I dropped it someday 3 weeks ago and since then my instructor has also been kind of annoyed by me, I see sometimes when I do something bad he just shakes his head and turns away. I felt so shitty and since then it goes up and down, I have every week a driving lesson and either I drive totally super or just ride grotto bad.. last time then everything worked out great again but this time it came to it again that I was probably not really focused and while staying the bike has fallen on me again. Since then I have totally depressed my teacher immediately afterwards said to me actually he would send me home now w because everyone who overturned a bike 3 times is not made for it.. he wanted then that I put up the bike alone what I just didn’t manage no matter how much power I used and he had to help me again because I was just too hard. Today I also watched over 40 people on a public place because I felt even stupider then. We did then still a little further and everything else I got again well I don’t know if it’s because the bike is too heavy or too big, if I really just don’t concentrate enough, because sometimes it works out quite well or if I’m really too stupid for it and should stop. My instructor wasn’t even sure at the beginning if I can touch the ground at all but he meant as long as I can get down with my toes I should actually get this done. In the end, the Spr came again. uch that I’m the only one who lets the bike fly and when he noticed how sad I was he just meant I should go home and howl. I get along well with my riding instructor as I said and know that the last sentence was just a fun one, but that really gave me the last kick. I don’t want to anymore if I know that I’m going to have a driving lesson again and I don’t feel comfortable on the bike for a long time, I don’t know what I’m going to do Is there any advice for me and would you tell me your honest opinion if I should just leave it or if it might be due to the motorcycle?
