Omg. I'm so very very sorry. I don't have the right words. I'm sure you guys will go through a million emotions. Talk to us when you need to. Or just lurk when you need distraction. Or post. (Lurking helped me get through some tough times when I couldn't think of what I wanted to say). I'm just so sorry.
Holy crap. I am so, so sorry. How is your H? Your MIL? I went through my grandfather's suicide. If you need someone to chat with/listen to you/commiserate with, PM me.
ETA: we are only a few hours apart. If you need something please let me know!
