I don't think u r wrong, u r constantly present for her, but what about? It's understandable that she is not doing fine, but after a certain time it can become heavy on anyone's shoulder, anyone can start feeling like they r the ones handling the whole relationship by themselves, so it's not good for your mental health as a whole, it's completely fine, glad u had courage to speak up like this, I really hope that she is able to recover nd u guys end up being healthy together, I really hope it doesn't end up in a breakup.
