Hi OP, I was in therapy once for four years. It is totally normal, especially if your therapist’s approach is psychoanalytic.
I would share your worries with him. The fact that you are concerned he would want you to stop is probably part of the work you need to do together…. For example, it is maybe reflecting your fears generally in life about not being wanted, or being a burden on your parents/ others you care about. being willing to take the time you need and want may well be part of getting over those fears. in reality, it’s highly unlikely your therapist is impatient for you to leave if you are still exploring and growing and sharing new things - ie doing the work! Those patients are highly rewarding to work with and therapists care about their patients and being part of these meaningful journeys. Steady income, while not normally the primary motivator, also tends to be a good, not bad thing!
It sounds like you are working hard and still gaining a lot and have much you want to explore, so assuming you can afford it, I would definitely keep going. What it’s worth looking out for, is if you start to feel one or both of you are ‘coasting’…. Kind of gliding along, not talking about the really deep stuff, just comfortably filling him in About your week etc….but it doesn’t sound like you are there. Some people continue even then…. Kind of like a weekly emotional massage, afraid to deal with the upset of parting. And again, if you can afford to, there are worse things! But as I say, doesn’t sound like you are anywhere near that point.
finally, you mention the fear of forming a deep connection with your therapist. You may well be at the point as you trust and open up more, of becoming very deeply attached in a way that feels very loving. Maybe even romantic. This can indeed be scary, and will likely connect again to your attachment issues/ fears. This is a natural part of therapy. The fears are valid, and for sure you need to know that your therapist is fully trustworthy and skilled, has your best interests at heart and is able to maintain the right boundaries…often working through your caring and your fears can be part of the treatment. If you are doing deep psychoanalytic work it can be very, very powerful and connecting. It can be beautiful, but like with any relationship in life, it has boundaries and limits. If you can use the attachment you feel with your therapist to understand your attachment style and grow, while staying clear on the boundaries and limits of the relationship, it can be part of the very rewarding deep work you do together. After a good and long therapy, it is indeed very hard to leave, but you will have learned that loss is a natural part of life, and you will leave with the resilience and learnings you have gained, hopefully also with a peaceful and confident sense of knowing you are valued and cared about, even beyond the period of your treatment.
it takes great courage to do this deep work, so well done!
