I just got through my first lessons that I purchased as a special during Valentine's Day from A.M. I do not have a partner, and so far I have been loving it up. All of the instructors have been fantastic. Now, with my first real purchase of several lessons, I went into the beginner's practice after the private lesson, and was in the room with only "students that have been taught there for 2 or more years. I felt inadequate. And one of the three instructors just let me go around and be clumsy .( who isn't at this point)( She was a 10 with the others) Today, the day after, I have this depression starting to overwhelm me. Is this normal, and is there any tricks to overcome it. I want to dance and be good at it.

Any feedback will be greatly appreciated, thanks in advance, Me.

You'll get better fast by being around those who know a lot more than you do. You wouldn't gain anything by being in a practice session in which you knew more than anyone else somehow. You always get better by watching others -- and then asking a lot of questions.
You'll be fine.
I am becoming rather surprised at the posts by beginners who seem to be expecting miracles. This art/sport takes a long, long time to learn and then just about as long to get halfway decent at it, and then a lot more time to get really good.
But it's a fun road, no matter how far you travel it.
