Hello Michele, so sorry to hear of the loss of your Mum, it is hard when we lose someone who has been there for us all our lives, and daughters do seem to grieve more. My own daughter Jo lost her Mum in April, and she has spent ages crying, indeed we both often end up crying when we talk about her Mum.
I want you to be strong for your dad Michele, he will need your support more than ever, because inside he will be hurting terribly too, support each other, and slowly with small steps you will get through this. Our favourite saying on here is to take it a day at a time. You will find some days will be worse than others, I still cry as does my daughter almost 6mths after our loss. People here understand, you are not alone...keep posting, it does help, it certainly helped me at a time when I even considered ending my life.
I doubt we fully recover from the grief we feel, even months after, there are people here including me, who still have a good cry when we think about that person we so miss, it's completely normal. It won't be easy, but in time you will manage to think and talk about your Mum and remember the great times you had, as I do with my wife, and if those thoughts bring tears, that's fine...let it out, but with time, one day you will be able to think about them with much fondness and smile, and those bad days will happen less.
Wishing you strength Michele, and remember...A day at a time.....
