Hi. I am in a similar boat as you. Year 12 (grade 12) and have recently gone into depression, and haven't been able to do homework in two weeks. I have luckily managed to do work at school, so I have still done good on the last two tests. I sadly had a biology lab due last Friday, and I didn't get it done because of my low mood and motivation, but talked to my teacher and she gave me an extension.

One thing I would recommend is talking to someone at your school like a teacher you trust. I have talked to one of my teachers and she has helped me feel better and not as bad about myself.

Could you talk to your psychologist and ask them to see a therapist or talk to your doctor to get them to refer you to a therapist or new psychologist?

Also, is there any way you could get an IEP or something equivalent to where you live? This way, you could get extensions on assignments because of this, plus additional supports in school.

If you need anyone to talk to, just message me . Hope things go your way soon.
