I am an anxious person in general and under stress, I pretty much just break. My anxiety gets super high and I sort of shut down. 

Sometimes, I'll talk to a friend about some general matter and this anxiety alleviates. But I find it unable to tell any friend or family member that I have serious anxiety because it feels like I'm burdening them and I don't want them to think differently of me. I want to do this because it is visible in how I conduct myself around them. It causes me to appear really withdrawn and sometimes, mean when really I'm just internally freaking out real bad and gone totally silent. I'll throw in some joke about "my anxiety" sometimes but I don't know how to say it to them that's it's a really bad issue and way worse than I let on. That it keeps me up at night and makes me write reddit posts asking for advice.
