The important thing is that you are in class. Friendship is important and you should feel comfortable while you train in class even if if is not at the 100 percent level. I cannot say this enough. If you are not having fun while training then you may be over training, or have the wrong training partner. Have realistic goals for yourself.
Progress takes time, commitment and most of all a reachable goal.
