I don't see this as a matter of logic. If you clearly feel that you don't need therapy at this time then you don't need it. If it's not so clear and one part of you feels like you still need it and the other one feels that you don't, just sit with all those feelings, turn your mind a.k.a "logic" off and let the decision come to you from the heart. The "logic" doesn't know what we really need unless it is in alignment with the heart, in which case the person doesn't feel any conflict or confusion. So, if you are not conflicted and if thinking about stopping therapy at this time makes you feel good then that's what you need to do. If you are conflicted, give your body enough time and space to process all emotions and to "deliver" its verdict. You don't need to figure it out. Your body will deliver it to you if you allow it.
