hair loss PLEASE HELP

hey all! i’ve been on lamictal since mid July started slow 50mg and now have been on 150mg since about October. I also recently started Propanalol for anxiety and have noticed a ton of shedding and excessive hair loss especially when washing my hair (i’m talking clumps coming out 3-4). Luckily I have super thick long hair but it’s freaking and stressing me out to the point where i could vomit bc I’m afraid it’s going to look thin at the roots or develop bald spots! I take it for bipolar. I started biotin, D3, Fish Oil, and Iron supplements this week. Has anyone dealt with this and what did you do to help the hair grow back?! How long did it take?! (I’m going to stop the Lamictal bc the stress of this isn’t worth it to me)
