But what do you want from therapy? And how quickly do you imagine should you be able to solve your problems? Problems can be very different - simple ones perhaps can be really solved with few sessions with a random therapist but the difficult ones might need wrestling for years with a good one.

Those therapists you have seen, have you felt listened to by them? Have you felt that they understood or wanted to understand where you are coming from. If not then these were no good match for you anyway. Also, if you want directive therapy and homework then you should look specifically for CBT as someone said but at the same time its directiveness can't guarantee you anything because CBT generally deals with surface level stuff. If you want to learn some skills and learn to observe your thoughts that's might be enough though.

I guess the question can be also what someone imagines the "root of the problems" to look like. Maybe people imagine that this is a place where you suddenly understand something and then you also understand how to make changes. What people probably never imagine or expect is that getting to the root of the problems is extremely unpleasant. There is a reason no one can get there alone because it is just so unpleasant that no one is able to force themselves to go there via pure will.
