I feel your pain...I have had some extremely difficult times the past year or two with episodes where I shut everyone in my life out. I think you should not condemn yourself for your vice, as even though it may be "bad", condemnation only brings setbacks.
Reaching out is the first step, or continuance of the journey, depending on where you are.
"Processing" your thoughts is very important, and when you are struggling yourself, chatting or talking with someone, or even working through the DBs like this is a good way to get input and help you feel supported and know you are not alone. Just the fact that I don't feel alone empowers me greatly. People are here for you...if you want to PM me go ahead...keep your chin up, and if you can, give yourself a hug.
-Love is love when it is free; love is love when others don't feed on you as a "need". If we reach one person with betterment, and in turn that one reaches another, what power we have to change the world."
