Yes, you can do this. It will feel uncomfortable to talk to others about the anxiety, but that is what you need to do. You will just have to bit the bullet and do it. I'm not sure there is an easy way to do that. Just remember you aren't one of those people who is drug seeking rather than having a legitimate need. Go in with that in your mind. Offer your T's number to the doctor and fill out a release of information form if you are comfortable doing that. That will help support your need for medication and if the doctor has any questions about the legitimacy of your request, he will be able to double check with your T. Honestly, I don't think the doctor will give you any problems with this; it is mainly your fear, but perhaps that will help. Hope it all goes well for you.
