I agree with Dust on this, stop drinking now if you respect yourself and this profession. You have to find and use better ways to deal with the stress of a troubling or bad call/shift. If you are this way after only one year... just imagine how it can get for you if you don't change something. Like Ruffums said talk to someone you trust co-worker, friend, pastor, shrink,etc.
Hollywood already portrays us in a somewhat negative light. Self-destructive, mentally unstable, with alcoholism, gambling problems, drug abuse, you name it.
Obviously it sounds like you really need help dealing with the stress of your calls. You may be good at your job hands on, but some people just are not cut out for it mentally. That is what you need to figure out for your own sanity and happiness. And for the profession of EMS.
And maybe you just had a crazy night getting to drunk for the first time. Just be careful. :wink:
