I'm so sorry you're going through this. Five months is a long time so maybe you've used up all your ways of coping with the teletherapy situation. Panic attacks are normally a sign of overwhelm. I know from your posts how painful it is not being able to see your T in person and I absolutely get it as I found it hard enough when my sessions were via skype I can't remember how much you've shared with your T but if you feel able to I honestly think it would be a good idea to tell him how much you're struggling with not being able to see him in person. It's clearly really affecting your mental health so it's important for him to know. Obviously he might not be willing or able to change the situation but maybe he can help you cope with your feelings better or even suggest when your in person sessions can resume. Often the not knowing is the hardest thing. I really hope you'll be okay.
