I'm tired of always thinking i will get sick and throw up. i'm just tired thinking every second every minute i will throw up. how can i help myself?

You need: some counseling and help from a Mental Health Professional...this thinking is what is called "obsessive" and may be part of a "larger" mental disorder! Speak with your Primary Care Provider for a referral! Good Luck Hope this helps! Dr Z

See a doctor: See a doctor and see if they can help with your fear of this. A psychiatrist might be a good option.
