I am not sure

Hello. I'm new to this group. I have Generalized Anxiety Disorder, but the past few months have been rough, i was told that i might also have depresssion (haven't asked my doctor about that yet). I am not sure, and i do not want to assume. So, I tried online tests (the more legit looking type) and they say there's a high possibility that i am. Im also not sure if thinking about death ( ie. how am i going to die, what if i die today, what if i drink all of my anxiolytics) is considered suicidal already. But i admit to self harming, even way back when i was in highschool. I can't talk to my parents because they're not as open about this issue and they'll just scold me for thinking that way. I can't tell my doctor about it because i'm scared, everytime i try to my tongue just roll back. Aside from that, i feel like i'm too aware that maybe i'm just making it up and jut overthinking and it actually isn't true.

I still am a student, and it bothers me, 'cause if i return back to school (and i hate school) it will become a lot worst, i might do something to myself, Please help me. I'm sorry if this is all overthe place and messy
