I have depression myself, it's very mild these days through my own tinkering of certain things in my lifestyle, but I was seeing someone who had overwhelming personality disorder and fairly regular breakdowns and that was the most exhaustive period of my entire life.
That was probably the moment I realized I cannot maintain an all encompassing relationship without deteriorating.
So from one mental health sufferer to another, be careful man. You're probably stronger than me in that area, but still.
That shit aside it seems like you've met someone you genuinely like, given she basically snagged you and reeled you in from your single and happy life lol. Good sign!
