Replying to Life/High School problems...

Hey guys, I've been feeling pretty shitty lately, and I wanted to vent to you guys about this. I know this will likely be taken as a joke, but please try to be serious.

I'm currently a freshman in high school. I look around and it looks like my social life totally tanked.

Not quite sure what happened, in 7th grade I had a lot of friends (and got middle school chicas), in 8th I still had a decent amount (this year was the year that I basically had no girl friends) and currently in 9th I feel like I only have a couple friends that I am close with, and hardly any girls that I am friends with and I feel kind of worthless.

Maybe my self confidence plummeted or something. Please offer some advice to a kid that generally feels down in the dumps right now :(
