developed stutter with jaw jerking

developed stutter with jaw jerking I recently went through a fairly traumatic event (not my first by any means) but not long after (the second day) i have developed a stutter. It feels like I can’t get the words out sometimes and my jaw does this weird sudden jerking movement that’s obviously visible. I am also on mental health meds (Bupropion, Lamotragine, and Trazedone) but I’ve been on them for years. I forgot to fill my prescription for the Lamotragine so I went one day without it but I have done this in the past and never had this kind of effect. I’ve read here that it can be trauma based so I know that could be a possibility. Probably a stupid question but will this stick with me long term now that I’ve developed it?
