should I get my GED?

I’m just so tired of school. I’ve missed almost this whole week because I pretended to be sick. I’m failing a lot of my classes now because I just don’t want to to do the work anymore. I don’t care about what I’m learning and it’s making it hard for me to keep working hard. I’m 17, I’m a junior, and I actually have more than enough credits right now (I have 47 and you only need 44). my gpa is actually and 2.7, so overall its alright and I did well on all of my regents and I’m taking my SAT in 2 weeks. but I just can’t bring myself to go to school or do anything. I just want to go to college already! it would be nice to end class early or have it at night and actually learn stuff I care about. but I’m so tired of high school! what’s so bad if I decided to get out right after I finish this year (then I’ll become a senior) and just take it this summer? I mean if I stay any longer I’ll probably fail everything. right now I’m already failing english and math, so I’ll have to take it next year again during pm school or something. I never used to be like this.. I guess I’m really sick and tired of it all…
