One thing of all we can't help just like that, you need to help yourself.
First, if you want to get a new mind set, start talking to yourself, and pushing yourself. For example, in school if you had a bad grade on a test, you will tell yourself to study better, and work harder to do better. This is the same concept in PUA understand your mistake, and approach each problem multiple ways before you find the one that works best. For example when I tried to chat online with girls, my conversations in the beginning never got good responses, I thought about it, even asked my sister, and tried something different each time until I got it right, now chatting online is easy. When that is the case move on to the next step.
Second, getting over AA is simple, yet few people realize what they need to do, you can read all day get all the tips you want. But it wont help your AA. To get over AA, just talk to girls, approach them, crash and burn, approach them crash and burn, and so on. That is the only way, get over AA is like asking. What is the best way to do my homework? ... Well, just do it.
Think about it this way, if you were a really good PUA, and you were assigned to kiss some girl in 10 minutes, well, I think at that point in time approaching would be the least of my worries
Also try this, go out with a friend, give him 100 dollars or euros or whatever. And he pays you back 10 dollars for each time you approach, if you don't approach your friend keeps 100 dollars.
