Depression, PTSD, School, Anxiety caused by Sexual Assault

I recently spoke out about my sexual assault/rape. It happened in November 2018 and I spoke out about it April 2019. NO ONE knew. I recently started therapy/couseling after already have been on medicine for depression & anxiety. I do online highschool, my grades are extremely failing my highest grade is a 34% there is no way i could pass the year. I have been severely depressed and haven't been able to do my assignments and i dont go to public school for reasons. Im afraid that i may get kicked out of school and be forced to go back to public school. Is mental health and trauma recovery not important to the school system? Is this a reason for an unexcused absence? 😪
