Instead of sitting there feeling like you are going crazy (we have ALL been there)- be proactive and productive about it all. If you can't get into a detox center right this moment, go to the hospital and let them know the situation and they will be able to safely detox you and provide you with the proper medication to help you get through this.
Also, it is time to make a recovery plan. First step would be to take accountability for relapsing, no one can make you drink. If you have a friend that is pressuring you into drinking then that person is NOT a friend and it is time to get rid of that person and anyone else that is not supportive of you finding recovery.
