I've had this struggle SO much. Trust me they aren't your friends they are just using you to get what they want. For example, I had this friend (we'll call her T) So one day I really lost motivation and stopped drawing (for around a year). Well, T wasn't happy that I wasn't drawing stuff for her anymore so she told me "you're so worthless" and she stopped being my "friend" and spread rumors about me and using my art and telling others she drew it.
Short story long, Some people are not your friends if the only reason they reach out to you is when they want something. The best thing to do in this situation is to honestly just walk away as much as it might hurt, it will hurt worse when they are the ones walking away
