My opinion might definitely be a minority opinion, but I want to share anyway.
I am sorry for this pain and confusion you are going through. It sounds maddening and I can imagine a little just how difficult this is.
Yes, there is a lot of transference going on, and perhaps it might be really important to talk to your therapist about it.

BUT, I can also understand your thoughts on perhaps quitting or finding a new T.
And sometimes, just sometimes, that is not the worst option in the world. A lot of people always say that transference is good and helpful. It really is not as easy and black and white as that.
There are definitely times when it is VERY helpful. But there are other times when it is not helpful at all, when it hurts and harms more than it does good and when it interferes completely with the actual issues that made you look for help in the first place. When the therapist becomes an obsession and this obsession is what you pay for but the issue around this obsession is not resolved, it become very thin ice and it can cause immense pain. And worse, when it interferes with spouses, family, friends etc. - it can trap us.

My therapist believes that transference is normal but should not be fed or encouraged. She says that in transference she can learn a lot about the underlying issues of a client, but she can also see how much of a comfort space her office can become, when the client depends on the therapist to fill their needs. After a while the client might become unable to live well without this comfort and when she tries to gently push towards resolution, some clients feel rejection and hurt and feel they left therapy worse than they entered. Not all therapists are equipped to deal with transference in a way that helps the client.

And, not all therapists believe that transference is vital for the healing process, some think it is a side effect of therapy. And like all side effects, sometimes they are worse than the ailment we were hoping to cure with the drug. So with medication, when the side effects become too strong, we change medication. With therapy it's not that easy, but there still needs to be a change in direction.

Perhaps for you, it might be more helpful to have a female therapist and you could work through the feelings you have developed for your therapist?

This might sound weird, but I do believe you are right when you say: " I will feel crappy for a little while, but have a chance of getting T off my mind for good."
Yes, you will feel crap and in pain and you will probably cry a lot, but eventually it won't hurt that much any more and it might open the opportunity again to work on your issues again.
I absolutely do not see this as running away at all. Not all issues have to be dealt with right away, so your father issues can still be dealt with, perhaps in a gentler way.

I have to share another thing my therapist said: "Everybody at one time or another has to deal with a broken heart. But not everyone who has ever had an awfully broken heart, needs therapy to get over it, but they need to have love for themselves and time to heal."

I think what I want to tell you most of all, that I wish you have love for yourself and compassion for yourself. If you can't work through this with your therapist (But I hope you can of course!) then I hope you will make a good decision on what is best for YOU.
You are in so deep with this these feelings, and there is such a thing as being in way to deep to be able to get out without help.

What this help is, is up to you (and perhaps your therapist) to work out. Or perhaps a break from therapy might help. Or a gentle transition to another therapist. Only you know this, Clementine. And I genuinely hope you will get the help and have the courage to ask for help.
