helpme deal with my friend (long post)

so uhm i got this one friend whos diagnosed with bpd and depression. we met online but ive seen them multiple times irl so i did consider them as one of my friends.

so just a while ago they bursted out to me bcs they noticed that i removed them from my private social media account. i explained that i removed them plus all my other friends because i want to delete it (i dont rlly use that account except for game clips and shitpost). they kept on saying that they feel left out and i dont consider them as my friend etc. they also mention that they feel lonely bcs i didnt text much and they thought im distancing myself away bcs i hate them or smth. i explained myself so hard that theyre important in my life
and i didnt even hate them one bit. rn they dont reply to any of my text and im getting anxious.

i know this is not about that account and all
but i did think that this is kinda my fault for making them feel that way bcs im a bit closer to another of my friend but in the same circle. i mean the closeness is only in the surface bcs we dont even talk that much except when we’re in game. i genuinely never think of it a big of a deal bcs i rlly enjoy being w them both equally but ig the other one think otherwise.

just to be clear, i genuinely think that removing someone from a social media isnt a bit of a deal(they also had one that they think i didnt know but i lowkirkenuinely dont care.) i did think they react like that bcs i was more closer to idk if its important to mention this but im also not a big fan of texting constantly. i can go days or months of not interacting with my friends and i can still talk to them normally. i did say this to them multiple times, that im not a big fan of texting constantly, but ig reassurance is rlly a big part of their life.

i feel like im obligated to stay by their side atm but this is not the first time that they burst out like this so its rlly starting to burn me out. i asked others for their opinion but i think that i need stranger’s opinion on this bcs i rlly rlly dont know how to feel. plsplspls help me out TT
