Hopefully, you will feel good again...if nothing else, you'll get to where you feel good some days and not so good on others, which isn't SO bad.
Effexor is a good drug, one of the best AD's for chronic depression, IMHO...and don't forget excercise, proper diet, getting out of the house, therapy and peer support; you know, all that stuff you REALLY don't want to hassle with...

It's all very important to recovery.
Good Luck...
