Ones attachments and feelings towards a therapist completely relate and connect to ones relationships and feelings towards other people in the world. Dealing with the feelings and things that go on in therapy help deal with everything outside of it. If one gets obsessed with their therapist that expresses problems such as attachment problems or lack of self esteem and a bunch of other things. Also, I might be attached to my therapist and have gone through periods of obsession but have gotten through it and it has made me more self aware and has helped me with my problems. Another thing is that it is all worth it because without therapy I wouldn't be alive right now and everything and I seriously mean everything has gotten better, maybe I have step backs and some things havent gotten noticably better but I can see a bunch of improvements. You have to understand that therapy is just another relationship and if problems occur in the relationship it expresses problems in others as well.
