My house alarm went off around 2am and it turned out to be a false alarm. since then, ive been extremely anxious and have trouble sleeping and i can never finish my dinner because i want to throw up whenever i eat. what do i do to fix this?

It is not feasible to fully understand the rationale for your intense anxiety based upon your brief post. Would recommend you get proactive and seek counseling ASAP. Have found that cognitive-behavioral therapy is highly effective, but might also consider biofeedback therapy. Addressing your emotional reactions at this point could truly enhance quality of life.

Even though this unpleasant for you now, following through w/some support from a psychologist can have lasting benefits for the future. It may be that you already had a low-level anxiety disorder. Please remember that we all get anxious at times and when appropriate it can help. Peace and good health.
