How could meds make me better if they will not solve the root of my depression?

My therapist has been trying to convince me to go see a psychiatrist so he can hopefully help me out of this depressive mood I’ve been in for the past year or so, maybe with medication. However, I’m reluctant because I feel like meds will be a temporary solution to a permanent problem. I know my brain chemicals might be all scrambled since depression does that to you, BUT I feel like taking meds will not make me better for good, because my brain will still keep going back to those dark places that make me feel the way I feel, and I think that it will simply never change.

I wanna get better but I don’t think I ever will because I’ll always have to deal with myself.

Am I wrong for thinking this way?
