I really don’t know what to do honestly I recently started hanging out with my childhood best friend and discovered they had bpd I’ve been supporting and helping them from the start , but I noticed that they barely took their meds so I told them to seriously start taking them or they’re going to relapse ( I take antidepressants and I know how shitty that feels ) so they started taking them again , and now I found out why their meds haven’t had that much of an affect and it because of their frequent drug use I know they do hash and stuff and I know they did xanies pills and acid I but they keep on telling me that they don’t and I’m really worried about because they’re moving away to another country in a week or so and I’ve been trying to help them but they keep on pushing me away and we don’t get along anymore , I’m really worried not to mention that they’re extremely attached to their s/o who’s a senior ( my friend is a sophomore and he just graduated I think ) he’s really nice but whenever we hang out she asks if he can tag along and I honestly didn’t mind it at first until they just started coming over to hang out or have a quickie w the s/o and barely talk to me like sometimes they’ll literally come and text their s/o the whole day and I hate it , they even asked if he could come to my fucking birthday party and all of that made me push them away as well , and I feel extremely guilty because of what they’re going through so I never bring it up or mention it because I don’t wanna hurt them and I seriously don’t know what to do I feel like crying just thinking about this shitty situation even all my friends around me are telling me that my friend is going downhill and they’re a lost cause and I can’t help them and trust me I’ve tried everything ( I think they’re an addict and I can’t do anything because we live in asia and rehab is not an option for people our age because of shame culture their father would disown them)

I don’t know what I’m allowed to feel and everything feels wrong especially when I feel like giving up or no longer hanging out with them even though they’ve repeatedly pushed me away and hurt me yet I still love them but I don’t think I can do anything

Please tell me how I should feel or what to do

I can’t take the guilt anymore because I’m slowly starting to care less
