I feel like you are severely overthinking things. As the brother said, doubts do not break wudhu. That's all there is to it. When you pray,
only if it is 100% obvious to you that you have passed wind, should you then make wudhu again. Otherwise, continue as though nothing has happened.
the problems that when I feel it coming down and I try to stop it I dont know if I am sure that i didnt pass the wind or not
See, you say here that you are not sure. If you are not sure, then don't worry and continue as though nothing has happened. You essentially need to train your mind into not being too anxious.
Also, if you have a lot of wind to remove, perhaps doing a number 2 might help in alleviating the build up.
