What would you do if your friends started to drain you emotionally?

 It depends on the specific circumstances and the nature of the emotional drain. If it's a one-time thing and a minor issue, 

I might talk to my friends about how their behavior is impacting me and try to find a solution together. If it's a recurring issue and it's causing significant stress, 

I might need to reevaluate the relationships and consider limiting or ending contact with those friends. It's important to take care of yourself emotionally and surround yourself with people who uplift and support you.
