I miss my Dad too :( I'm very sorry for your loss. Of course you will still be sad 4 years later because it IS sad. You aren't expected to move on, but eventually you will cope a bit easier and manage your grief. I imagine it being really hard without having your mom as you grow older and it sure isn't fair. You aren't alone in feeling this way, I have also been crying every day. Have you tried grief counselling? I just started and I reckon it is going to help a little bit. Wishing you strength and lots of love. x
