Two suggestions

1. Follow the suggestion made by most correspondents of the post -- move on, the chemistry between you and A is just not right, and it's just not going to work. To be more precise, if you cannot deal with A, that's just not your company, you just have no business or work there, that's just not the place you can make money. The solution is simple: find the place you can make money, and the key is the supervisor there likes to take you, and you can deal with that person.

2. Go the other way around, just go ahead and do whatever you have been wanting to do. Again, it's a free country, people should be free to do anything they want -- for example, give themselves. To be precise, the move you have been planning is not much different from suicide, so just go ahead and do it.
