Oh dear @misschance, it could be stress for sure or a side effect of medication of course as you pointed out.
I wouldn’t do anything about it without an expert advice... it could worsen things. Stay calm, wait for your appointment, maybe cut your hair (you will be as beautiful, don’t worry) and don’t worry too much ( to lower stress). Keep your mind on other stuff, all will be ok sooner than expected 😉
Sending my best wishes and vibes over there as well as a ton of 🤗🤗🤗
