I see.
I have seen nearly a dozen therapists over the years and several were duds, one was beyond unhelpful.
On balance, the Ts I have seen have been professional, smart, caring, ethical, and have given me enormous practical and insightful help to get past depressions, romantic heartbreak, and an 8-year period of either unemployment, unhappy employment, or unstable employment.
I don't understand completely why you are reasoning that a couple negative experiences mean that therapy isn't an important key. Maybe that's your depression thinking, not smart logical you...?
I wish you whatever help you will seek and accept, dear Bones, to lift you from depression to new kinds of action and imagination that can help you find satisfying work, and satisfaction in the small joys of daily life.
