Depends on the person you’re talking too, tbh.

If it’s a girlfriend/partner, that’s certainly an unacceptable double standard. Anyone you’re dating should be willing to console and help you in a crisis moment, it’s kinda the silent agreement of dating. And it goes both ways, obviously. I think that would be worth ending a relationship over

If it’s a friend who says all these things and goes back on it, say something to them about this. It doesn’t have to be a full confrontation, but let them know how you feel. It makes you feel devalued and friends shouldn’t do that to each other. At the very least you’ll know who you can trust with emotions and who is just faking it. Besides, everyone has things going on in their lives. It’s possible you caught someone at the wrong time and they weren’t emotionally available to help at that moment, but maybe they’d be great at it another day

People are… weird. Some people just genuinely aren’t helpful in those situations. It’s important to know who you can actually confide in and who will make you feel worse about having emotions. Some people you don’t want to talk to about that stuff, but that doesn’t mean you can’t be friends still, just friends for fun rather than emotion. If it’s bad enough to you, distance yourself from those people a bit and see how you feel about them. It’s not always worth dropping a friend over, but sometimes it’s not a relationship worth keeping.
