depression....

okay so on thursday i met with my consular and we talked about all my problems and everything... i felt so much better and on friday i started to miss her really badly, and i got sad over the weekend for no reason. i tried to tell myself positive things, it’s going to be okay, this isn’t your fault etc. but i cant seem to push the positive thoughts into my head, i just feel like i’m never going to get better... i’m trying so hard. any tips or advice? i’m in high school and the consular is only there during school.. i’m 15 and i’ve been struggling with this for a year, i just need something to help me fucking feel better.
