controlling breathing a thing from voicethoughts

so the thing is that i cant breath right and everytime that im doing something that is necessary like sleeping the voicethoughts would control my breathing and make it to fast or to slow to stop me from breathing. this could cause me to feel like my nose is stuffy sometimes and even give me the wrong understanding of what it is that im doing like if im taking a task seriousely because i feel my breathing is alright or if i have no intrest in a task that i find useful for me to do.
