I helped a work friend who dropped out when she was 14 (she was pregnant) and had spent a long time getting her GED (in our state it requires lots of special courses first, in addition to the test so check out your location's requirements before you think it's "easier") and then was trying to get a college business certificate and finally had to drop out of that because working and taking care of her family and the "learning curvre" (I was tutoring her in the remedial math she had to take) was just too much for her.

I'd tough it out another year if you can so you'll have more choices later in life when you may feel better and want to move forward easier.
