So much stress

I have been dealing with social anxiety all of my life. And after 40 years, I finally put a name to it. The last few years have been out of control. And every day feels worse. I have so much stress that I can’t sleep at night. I have the worst acid reflux. And I feel overwhelmed. I have been doing a lot of research and I think I understand much of my problem. I suffer from social anxiety, HSP, and codependency. And the more I learn, the more I believe I am married to a narcissist. I feel lost. And hurt. And alone all the time. I have been isolated from my family and friends. And the only people in my life are her people. I don’t have anyone I can talk to. And everything I do in my life drives away those that could be there to support me. It is scary. And lonely. And painful. And I don’t know what to do.
