Hello alnlane,
I think it is very brave of you to come here and let us know how you are feeling. I am really glad you did. I have struggled with generalized anxiety and PAnic Disorder with agoraphobia for many many years now. I have also suffered from burn-outs and depressions since I was in my early teens. I know how dealing with that kind of stuff feels. I also stress out and worry about my health. I have now banned the use of internet for disease checking as it aggravates my worries!
Anyway, I wanted you to know, I know how it feels to feel like you had a relapse. The beuaty of it is one can get out of a relapse. When my panic disorder and generalized anxiety relapsed a year and a half ago I went to The Panic Center. It is great! It helped me a ton. Now that my depression/burn-out seems to be back to haunt me I am here on The Depression Center. Have you tried the Panic Center for your anixety? It really is quite helpful!
As for your therapist, if you are not happy with him/her, I do agree that finding a new one is a great idea. One is allowed to shop for the best care possible!
As for your family, have tried talking to them and letting them know how you feel. Sometimes we tend to be hard on ourselves and think we are bringing people down and yet that is not how they perceive it!
Be kind and patient with yourself. Take care. Sorry I could not be more helpful.
P.S: I talk here about my relapses so you know you are not alone. But I do want to tell you that even though I have had this since I was a teen, I have had an overall good life. Living with all this happily is definitely possible.
