Taking Meds and Going To Therapy?

I was hospitalized in 2017 for PTSD, anxiety and major depressive disorder and I remember being put on so many meds that I was either zombified or very high. I'm not at such a low point now and have since been off of meds and out of therapy, but I'm in this cycle of lows that seems to happen every year around this time. I stop going to classes, do very little schoolwork, and struggle to get out of bed every morning. I'm thinking I might need meds and therapy again, just not to such a severe degree. Any advice?
