So basically I havent had a good friend in like 4 years, and a couple days ago I met smn online and we can talk for hours and she's super kind to me, but now I'm feeling too attached to her because if we don't talk for too long is start getting really anxious, same thing happens if she suddenly stops replying for a bit. Does anyone know why this is? Also sorry if this is the wrong subreddit but idk where else to post it
