ADHD/ADD medicine making me lose hair ?

Legit freaking out at the moment . I take vyvanse 70mg for ADD everyday , once a day . I started it over a month ago but started out with vyvanse 60mg in February and I've been on and off as a child . Well I'm losing my freaking hair . Like clumps and chucks and it's horrible . I had volume and my baby hairs grew after I got pregnant with my second baby and he's 4 months . So how did I go from hair goals to hair loss ? Like what can I do ? I'm thinking about stopping this medicine and moving to Colorado or something so I can get prescribed cannibis for my ADD and Anxiety attacks (On top of taking vyvanse I take xanax for panic attacks and anxiety) .
