Will they think that if I tell them I think i have BPD it will be “another one of those illnesses that she thinks she has..?”

I have had a long struggle with depression, anxiety, anorexia, bulimia. I was also diagnosed with cyclothymia which Ive never felt quite fits, and tested for autism which proved negative. But always feeling as though there’s something about me that isn’t right, I can’t tell if I’m being overly dramatic, or I’ve finally found what could be my answer. I don’t want to bother them about it because I’m worried they’ll judge me and imply that I’m just trying it on with them with every possible illness.
