Will I be kicked out and will I lose my GI Bill.?

I am an E4 in the marines who has been in for nearly 3.5 years. I was recently diagnosed with anxiety and I'm still awaiting treatment. But during the course of time without treatment I havent been able to qualify on the rifle range. I have unqualified 3 times within a 6 month period. Before the symptoms of anxiety I was a 2 time high sharpshooter. What consequences am I going to see???
