Failing classes, deteriorating health, and no direction in kife doesn't sound very "functioning" to me. Some alcoholics, like myself have never actually dealt with the regular stresses of life because instead of actually feelimg fear or insecurities we drank instead. The good news is that it is normal to feel like that. I am also sometimes shy, but that is what makes me ME. As I move forward in my recovery I feel more and more comfortable in my own skin and you will too as long as you put down the drink and make a decision to change your life(and have enough honesty, openmindedness, and willingness) to work a program of some sort, whatwver that is. Have you considerered going to AA? I myself go to AA meetings and I also come onto SR to check the forums. That's what works best for me. Would love to see you give it a good shot. Sobriety is wonderful and if I can do it so can you.
