Like the others said, that is sad to hear.
If someone isn't coping then people should always try their best to address that and help out. I hate when people say it, because even though it's true that someone somewhere has it worse, that doesn't mean you don't have a right to not cope.
All of us are human, and no matter what situation or circumstance we should all have a chance to express it.

My advice would be to bring it up again, and explain it like I did. You should try to create it into a discussion so that it will engage those people and that they will be made to think about it, instead of just dismiss it. Tell them how you feel about their reaction (saying that other people can have it worse), and describe your situation of how you are not coping. Tell them that you would appreciate support and comfort, some help.
You should say that you could cope, like those other people, but that is only if you get the help and support you need.

I hope this works for you, and that soon you'll be alright soon. Good luck
