The more you read here the better you will be, you may not feel better exactly, but you will understand that there are people here just like you feeling the same feelings you are. I am no where near a good DB'er, but I try. Right now, I am floating, just going with the flow until I decide it is time for me to rock the boat. You just do it day to day. Don't worry about tomorrow, focus on you today! I still have problems concentrating. I am working on my Master's degree online, and it kills me to sit at the computer and think about something other than me, H and our M, but you have too!
