Hi mcrnvl. Welcome to Psych Central. Sorry you are feeling unsettled and mind is going full tilt. My experience is that talking to psychiatrist to get meds is very important to avoiding full manic episode. If not available quickly, ask your doc or therapist what might help.

Hope you find the resources you need. I find high protein diet with low carbs and frequent meals or snacks every 3-4 hours or less helps keep me more stable. I also exercise and do yoga.
