Oftentimes people ignore that depression is also a product of a system that prioritizes profit over everything else including mental and physical health. You can go to therapy all you want but it doesnt put more money in your pocket or lower prices to lower financial stress, decrease food insecurity, doesnt increase job security and satisfaction, doesnt give you back the time your employment has robbed from you, doesnt improve relationships and your ability to form them, doesnt make third places pop into existence, etc. Therapy cant remove those factors that cause depression in the first place. I have increasingly heard stories of people going to therapy only for the therapists to realize that they literally cant do anything about the stressors because modern life is so systematically stacked against the individual.

Depression can cause permanent changes to your brain and thought patterns which makes it more likely for you to relapse or slip back into negative thought patterns if the right pressures are added, which is constant today. Therapy can provide alternative ways of thinking and coping mechanisms but cant completely remove those pressures which are outside of your control.
