Does anyone ever have those times where you’re doing just fine, but then suddenly you think of the worst case scenario for something and your anxiety just floors you! I’m coming off of a pretty overwhelming week, and last night I was doing fine and relaxing when suddenly that happen and it sucks. I know I’m just overthinking it and it probably won’t happen, but a voice in my head always says “you can’t be so sure.” 
Anyways, if anyone also does this or knows of anything that would help I would love to know! Thanks!
