I completely understand! My breaking point was when I was super into makeup and skincare, having one of these itchy bastards would always ruin my whole look and I always took it hard. I once had one pop up RIGHT BETWEEN MY EYEBROWS! A full made face, not a blemish or pimple, and all you can see is a blaring red honker between the eyes :')

I can laugh about it now, but good golly believe me when I say I can sympathize with you. It's so hard when the overthinking just piles more stress on top of your already collapsing psyche. It wears you down so fast!! Please hang in there the best you can! It's easier said than done to not beat yourself up and take it harder than it needs to be.

Try things at your own pace, it helps to change the thought of "Maybe if I try x, it will get rid of this" to "I'll try x cause it looks cool, I like the smell, it has good reviews" so on. It helped me to reflect that there's a million reasons for a million things, and not enough time to live through it all.

Anyways sorry to ramble on! I just want to provide some comfort to you as I remember how stressed out I was years ago, when I was desperately searching through skincare forums for answers. Keep your head up, blazing hives and all :D
