I would suggest you start meditating for atleast 2 times a day and 15mins per session, which shall help you focus. Further, from now on I would like you to give yourself 2mins (120secs) to reevaluate every decision you take from now, even the smallest, which will help you be sure about your decision and won't bother you till results. Also meditating will help you relieve the fear and pleasure aspect. Taking one problem at a time.
Next Steps
next step would be to consult a counselor after a week for much better results
