I was diagnosed with depression in my 20s, though I had been dealing with bouts of it since my later teen years. Then in my 30s, I was diagnosed with depression and anxiety (GAD, I suppose). More recently, I self-diagnosed SPD. I had thought to end my life as a teen, but didn't want to add to my mom's pain since she was going through a divorce. I hadn't had any more thoughts like that until recently. I stopped taking generic Prozac fall of 2010 and since then I've had 3 incidents of those thoughts (2 of them including full panic attacks). I don't want my kids to grow up without a mom, so keeping them in my thoughts helps to not take action on my thoughts.

SPD symptoms can ebb and flow over time--seasonally or weekly or daily. Transition times are especially hard for my older son. So his school and I try to offer more support when there are big changes coming up, like getting a new teacher at the beginning of the school year or changing schools. Depends on triggers and what therapies are being done.

I suppose there is a relationship with all of them, all relate to neurons in the brain in a way.
