The responses here are some of the reasons why people with depression or mental health difficulties don't seek help. The media is all about seeking help, telling someone, not killing yourself, and then there is the reality, expressed here, that depression is such an ugly disease that noone wants to even date a person who is depressed.
Sure. Would you feel the same if your friend said that they've just met a nice guy, but he's severely physically disabled to a point where there will be times where she will likely need to be a main carer as well as main earner and childcarer, will mean he cannot join in or engage properly with social activities, travel or just hanging out in the evening and may cause him to be emotionally unavailable or potentially very angry (people on MN love to say that men who are depressed and act this way are abusive not angry, but it's a very common symptom of depression, particularly in men and even ones who didn't feel that way before) for an extended period?
My DH has required physical care and it was hard but fine. Severe depression nearly broke us, it's nothing like the low grade down that some people see it as here. If it develops after you're together, that's fine, but I couldn't in good faith encourage any friend or family member to start a relationship with someone who was in denial of severe depression. It's an awful illness for the sufferer, but also one, like addiction, that can easily ruin the lives of a whole family.
