I've been through this before too (and likely will again eventually)! I'm not sure I can help with ways to talk yourself through these things or anything (because i'm not able to sometimes). However, for what you're going through *right* now, it sounds like you are being hyper-aware of your body. If you think the slight vibration is something you'd notice even if the room was really loud and you were watching a movie or talking with people, then I think it's fair to ask a Dr. About it.
If it doesn't seem to be connected to any trouble, and the only problem is that you're thinking too much about it, then it probably would just be a waste to go see one.
For me, it helps (a little) to try and get my mind on something else if possible. Read a book, watch a movie, call a friend or relative...Anything not to think about it.
How are the mental health pros working out? I've thought about that before, but it's weird because my more severe symptoms only show up when i'm under a lot of stress, so I don't know.
