I really hate my new haircut!!! please help me?

I used to have long thick hair, all the same length, down to my elbows. Then my sister forced me into getting it cut so it was just past my shoulders, and layered. I hated this, so I went to a different salon and asked them to 'shape it' a bit more, and they cut my layers really short so it's too thin at the bottom and gave me a terrible thin side fringe that went all greasy. I tried thickening my side fringe myself at home, but I did it wrong and now it looks terrible!! I know I could poof it on top of my head but my forehead is all spotty (so is the rest of my face). Whenever I naturally dry my hair it looks AWFUL. I'm scared of damaging it so I use a heat protection spray and a low setting whenever I blow dry (which is every other day). Will that protect it? And what shall I do about my weird fringe? I keep crying and am so depressed. It's so awful, I never used to worry about my hair before I cut it! Also I'm so unpopular at this new school, the one thing people really used to envy was my hair! I'm nearly 14 and in year 9, and practically all the girls in my cl are such show-offs. I bet they're all so glad I look horrible now. Please help me :(
