I have anxiety over some thngis and I really don't feel comfortable talking about it with family. I have told friends and I am seeing a psychologist. I just really want their support, but if I say I have anxiety they will demand to know about what. I am planning to be ambiguous about it, but the amount of worry I go through can't be explained by just saying worrying about stuff. I also don't know if I should lie initially and then tell them the real story. What do you think is the best way to approach this?
