If it's making you feel nervous or anxious, then maybe start looking for in person help. Maybe keep your next appointment until you can find another provider. Can you do video calls or do they make you feel the same? I too get nervous or anxious on the phone, just knowing I have to do one almost causes a panic attack. So I get it.

I think that it is important that you let your current therapist know about how you're feeling. They may have some insight into some potential options that you can take with them or even it's possible that they have some knowledge/resources of alternate places to look if there is no option. I'm wishing you the best in finding a good therapy placement for you! I know how difficult it can be to find a therapist that works for you and your individual needs.

are video calls an option? I know that seeing the person alleviates a lot of my stress. Definitely not a perfect solution but if you like this therapist and can't see them in person it might be a good compromise

Trust it and understand what you're doing takes courage to do. Don't give up and don't feel stupid say anything and everything no reason to hold back this person doesn't know you right? And you're not going to be buddies with them. They are there to help.
