16 sophomore wanting to drop out

So I have always been a good student with grades but my attendance was never good I have bad anxiety in the mornings and I have 60 absences this year and the school has told me that they are holding me back and making me repeat the year so I decided that I really don’t want to do that I haven’t dropped out yet but do you think it’s best if I just stay in school and possibly have terrible attendance again or just drop out and get my GED. For my career I wanna be a HVAC technician and go to trade school which requires a GED or HS diploma what’s the best thing I can do from people that have experience.
