what is a good way to deal with grief?

First, I'm so sorry for your loss. You have my deepest compassion. Second, let the feelings continue to flow, they help to heal. Remember how much she loves you and remains a part of you always and be gently with yourself in this time of healing. Eat healthily, get good sleep and when you are ready, perhaps making a nice collage or photos book of her would help. 💜

Not really, you have to go through the stages of grief. Eventually happier memories will outweigh the sadness.
Very sorry for your loss.

Its a process and needs to take it’s course. Remind yourself that she wouldn’t want you to feel sad.
