Boyfriend developing bad anxiety

Hi everyone. So my boyfriend is in ROTC right now. He’s a junior in college so he’s got 2 more years before he can go active. He’s had anxiety all his life and has been going to counseling/getting meds for it before he got into college. Recently his anxiety has been getting worse because he doesn’t have the meds anymore and wants to go back on them but the army wouldn’t sign him off on it. Does he have any other options? Or does he have to drop out of ROTC/the army to get his anxiety medication?
