What should I do to get my mom lighten up?!?

Hello, I'm 15 turning 16 in March. I am currently in online school. I've ran away once, got caught with my 19 year old bf we are going through court right now because my mom is pressing charges against him for sexual abuse. After that I ran away again but ever since then I've been doing good, stopped doing drugs but my mom just won't let up its been 4 months, my grades have gone to straight F's to straight A's and I'm still not getting like a pat on the back or anything for doing that... I only have 3 weeks to finish half of a school year so im really stressed. I am really grounded and IDK what to do I haven't seen my friends in FOREVER and my mom won't let me hang out with anyone!! -sadface- I am feeling very lonely and like i cant talk to anyone because I have a horrible relationship with my family, and i know that's not gunna change. I want to know what could i possibly do to have her let me hang out with my friends she says she wants to meet them and blah blah blah i get why she does this but this is where it gets out of hand... She wants to see their ID and all of my friends either are too young to have one, don't have one or have lost theirs... SO what should I do?! Also if you know, can I drop out of online school at 16 without my parents consent? I live in Florida someone get back to ASAP:D it would help me emotionally and spiritually GREATLY!!
