Hi Marvel545,
Finding a good therapy is up there with the same weight of finding a good spouse. IMHO, the process is very similar of course the feelings and the relationship itself is different but the trust level and attachment needed are very close.
Now saying that, I have to say this much. First it is good you are becoming aware of your trust issue but what about your likability of a therapist. Do you like them as people as persons? I ask this (and you do not need to answer to me per se), just throwing it out there.
Sometimes our issues are soo ingrained and so deep, it may take a long time to actually open up. It is very easy to be functional at work, in a good relationship, but if you have deep self issues that you eat yourself up alone or in your head, then you can sit and talk about non-sense for a long time, until the mask falls. I think it is good to find a therapist you like, respect and you can even just tell them, I do not trust you but you are OK and I will come every week or biweekly or monthly whatever works for you but come nevertheless. Eventually, you start to think about this person, sort of them showing up in your head, like having a crush, and you hear their voice about topics and you start to just trust them naturally but the first thing you need without trust, you like them.
The education, the technique, all the other shiny things are nothing in human relationships. A therapist you like and you are not annoyed objectively speaking...I mean you can clearly see them as separate then you and as another human first, is priceless. Many times people meet others who can change you in a fundamental way in such a short time in passing and meeting a therapist can be looked at, do I like this person? Not do I trust them with my life? The latter is almost 100% hard to decide without knowing the person.
and that takes time, maturity to believe others can help, and extreme commitment and motivation to find healing.
If you are not feeling all therapists, it is just maybe you are not ready for a relationship yet. You are consumed by the one you have in your life, that you are psychic energy-wise, full for now. And that is OK too. Just take time off, think about it, and then try.
If for sure talk therapy is not your cup of tea and you are confident in a healthy way this is not it. Then maybe you can do bodywork, like a person who does the somatic work but still they will want to talk to you to find what is going on and these types of therapy also has it is own way of communicating by touch or body movement that you may find even harder than just sitting and talking. I would say try it. who knows?
I also was difficult in finding therapy but I realized at the end, I really needed one bad and I had to get over certain barriers mentally first.
Good luck. Not easy journey but you will find the one.
