Hello and welcome to this site. Sending you a welcome hug ..
I am so sorry to hear about what has happened to your family. I can imagine how shocked and lost you must be feeling right now. What a terrible thing to have happened. I am so sorry.
You will find lots of people here who can empathise with how you are feeling. We are sadly all here because we have lost someone we loved. It is terrible that such things happen out of the blue like this and such a tragedy.
I know what you mean about having lost your dad having been completely different. I think every loss is different. That has been my experience too. Just keep holding on. You have your daughter and will get through this, hard as it is. Talking helps, so keep talking to us here and on the Facebook group. It really does help.
