What happens if you go AWOL from active army for 25-28 days?

I was having problems well on deployment, I went on R and R and the problems kept happening and finally got worse i ended up in the hospital and let my chain of command know what was going on. I was diagnosed with adjustment disorder i believe or something like that. I got a psych eval at fort Stewart and was told i was not fit for duty, Now i am back at my duty station Fort Hood and have been doing counseling. I had an incident where I got very suicidal before even back at Hood and i told them about it and showed them things i had written down. During a day it got so bad i became suicidal once more and I ended up having the MP's come to the motor pool for me to make sure i was alright and they took me to the ER for help. They NCO's know about everything going on with me but nothing is happening, I asked my counselor if I can see psych about this and everything going on to get an idea of my mental status because i am scared of myself at this point and I was told that I dont have any serious symptoms that really need to be addressed..? I feel as if they dont care and are not going to do anything about anything going on with me. I have been very irritable with everyone lately and have depressive thoughts. Its driving me to the ground and i feel that i need to leave Fort hood for a little bit to clear my head before I hurt someone or myself or I do something to stop myself from leaving.... I just want to know what will happen if i was to go AWOL for 25-28 days
