Doubts and Ungathered Mind

I have asked questions many times here, and I have come to the conclusion that my mind easily tricks me. I speculate and doubt to a very great extent, and feel aversion to fear and effort; I will easily try to avoid such states. I feel these are all symptoms of an ungathered mind. For example, I often feel afraid of getting hurt from running as exercise, or just that it is too effortful; the consequence is that I avoid it. Similar with meditation, wherein I find sitting too effortful. But with meditation, there arises another problem: I also doubt, but I doubt all aspects of meditation. I doubt mostly the breath, and whether it is the right object, and whether I am meditating correctly. Ironically, I have read in meditation texts that the breath is *the* object best used against speculation and delusion. But, no matter how I examine the matter, I'm still uncertain that breathing meditation is right for me; I always tell myself "Maybe it represses my emotions," or "Such a person advised against it," or even "Maybe I'm meditating all wrong." Are these obviously just doubts which, despite seemingly seeing this, I cannot shake? Does anyone have other advice on this?
