How to support a friend who always leans on you but resists help?

I’ve got a friend who’s constantly in crisis mode, pouring their heart out to me about every little issue. While I want to be there for them, it’s draining—especially since they refuse therapy and blame themselves for everything. I’ve tried listening, offering advice, and even gently suggesting professional help, but they shut down or dismiss it. It’s like they’re stuck in a loop, and I’m running out of ways to help without burning out myself. How do you support someone like this? Should I keep being their go-to person, or set boundaries? I don’t want to abandon them, but I also need to protect my own mental health. #FriendshipSupport #MentalHealth #Boundaries #EmotionalDrain #SupportiveFriendship
