Are Antidepressants Buffering?

I have been in Scholars for almost a year. I have had a lifelong history of depression – not all the time but in episodes. I have been on an antidepressant for decades. Over my work in Scholars, I have discovered that I buffer most of the time – mostly with alcohol in the evenings and technology during the day. Without the buffering, and even with the buffering I am really depressed. My husband, who is a doctor, feels I need to go to the doctor and try more/different meds. Wouldn’t this be more buffering? Just numbing out with antidepressants to avoid the barrage of negative thoughts and feelings? I think I have low frustration tolerance for feeling like *ss and need to become less fragile.
