I’m not functioning

I haven’t been home since the 26th and I haven’t been sleeping well, last night when I timed it I had 5 hours, I’ve been either eating too much or too little, I’m mentally and physically exhausted.

My body is just extremely week at this point to where I stood up earlier I just felt weak and dizzy. My eyes are extremely red rn and I would try sleeping more but I need pills to make me sleep longer cause I just can’t fall asleep and I just don’t know because I’m not functioning anymore.
