I don't think there is "too much therapy". If you need to go to therapy twice a week or more, then it's totally ok! The important thing is that the therapy is working and that you have benefits from it, that your therapist is good and professional, that they challenge you and help you grow. If for example you go to therapy but the therapist isn't good, or there are red flags in their behaviours, or you don't feel right even after months...then you can go many times to therapy but it won't be that helpful. So it depends on the quality of the therapy.
