Everyone has something. Of course I want others to be happy, but sometimes life's struggles can be too much. I would (and have) date someone with anxiety or mild depression. I wouldn't go looking for someone to date like this, but if I really cared for him, then I'd date him.
No one is perfect. Everyone has their own problems and we have to learn to accept people the way that they are. No one chooses to suffer from a mental illness, and it is unfair to just treat them as less than others. I used to suffer from severe obsessive compulsive disorder and feel like I was worthless and did not deserve even friends. Others don't deserve to feel the same way.
Yeah, I would. It might be stressful sometimes, or scary sometimes (if he had suicidal ideation). But if I liked him and cared about him and he liked me back, depression or anxiety disorders or panic attacks wouldn't stop me at all. My closest friend has all of that (moderate to severe depression, anxiety, a few panic attacks, even a couple of auditory hallucinations when she was super stressed), so I know what I'd be getting into. The only thing is, I would have to know that he liked me too, and he'd have to be willing to open up to me about his thoughts and feelings and all that. If I just had to sit there not knowing what he was thinking or feeling, not knowing what's going on, and not being able to help in any way... I think that might be too stressful to take.
