Just remember that your mother would want you to move on. I also agree that if it has been three years and it still does that to you, you should seek some medical advice as that is not healthy.
Your stuck in grief. Not good. time to find help and get on with your life. God be with you. But it will pass if you want it to
ah, stay strong! It's really hard to cope with these kinds of feelings, but you know... you need to move on. You don't have to forget her, she was dear for you, but while crying and thinking about her, you are losing your life - your present moment. Think about it, would she be happy, if you would cry and mourn of her all the time? No, she is your mother, so she wishes you the best. She'd like to see you happy, not crying over her. Stay positive, I wish you lots of strength and I send you big hugs from here.
Stay strong Agnes, you'll pass this life moment. :)
Ohhh baby, ((((((((hugs))))))))). I'm sorry for your loss. I'm sure it will get less painful with time.
Your heart may never fully heal, but it's always best to look forward and try to live your life out in a way that would make your dearest mom proud.
