@alewis24 Check with your kidney transplant team, and speak to the social worker there. Let them know you are struggling, and are seeking some assistance. Kindly ask them for help in getting help. I know what you mean, so many therapists are really busy these days. You have to be persistent and keep at it!

Meanwhile, think about things you can do on your own right now to ease your mind. Exercise moderately, go back to a hobby you once did, or start a new one that interests you. Write out your thoughts and concerns in a journal https://connect.mayoclinic.org/discussion/journaling-the-write-stuff-for-you/
Do something creative like artwork or building something. Any or all of these may be helpful to you. What do you think?
