I feel like a piece of shit. So my friend has been in and out of the psych hospital ever since the beginning of quarantine. Near November of 2020 (when fake tics were trending on TikTok) my friend came back from the psych hospital for like the second time. But all of the sudden she had tics/Tourettes(not diagnosed) And I understand tics can be triggered but now she doesn’t have tics anymore, which I find fishy 😐 And a couple months ago (when faking DID was trending on TikTok) she suddenly had DID (not diagnosed) and is a system of 6???? She hasn’t  told me she has DID but I have seen her TikTok (100% sure its her) where she only talk about herself having DID. When I hang out with them I haven’t seen them switch but I know she is taking medication for her bpd which idk could suppress switches. I don’t know… it all seems so fishy. She has changed so much out of no where. There is so much more to this story but don’t feel like adding it in rn. She has had a now ex friend call her out on changing and being toxic all of the sudden. And I agree. She is one of my best friends but I feel like I don’t know her anymore… I don’t think I can be friends with her anymore… which breaks my heart. Any advice?
