Kinda in a funk

I'm a happy girl. I always try to smile, and be as positive as I can be but these past few days I've been in a really bad funk. Not sure why, ive just been feeling not so good about myself. It may have to do with the fact I'm not a major salesperson at my new job like a used to be at my old job. I think that used to help boost my confidence a bit. Yesterday, my managers did an observation on me and they said i scream no confidence with my body language. Kinda hard to hear. I just need to practice more and get more comfortable I guess. I'm also tired of being the new person!! Oh well, I guess it can only get better :( sorry for my boring rant! Just needed to get it out! Happy Sunday!
