Got a lot on my mind, need someone to talk to..

It seems like ever since my 14th birthday Im sad or depressed almost all the time! Theres too much drama even when school got out so that sucks, and on top of that the friends that I do hang out with are turning into huge jerks! Even my own best friend! At the beach yesterday its like she did everything possible to make me mad I just can't explain it, and plus everytime I do make a comment about something she says or does to me that hurts my feelings(especially in front of other people) she says something like well you do the same thing or something to just make it sound like its my fault and that just makes me feel worse. And since we were at the beach I didnt want to show my feelings , I guess?, I dont really know how to word it, but in the car ride back and at my house I couldnt stop thinking about it! and I went home and literally start crying, which is what I wouldve done but like I said i was trying to hide my feelings, I guess my point is I try to hide my feelings all the time and i always seem depressed but I dont wanna hide my feelings anymore and I just need someone to talk to...
