So sorry to hear about your grandma.
Sadly, there must be a lot of people out there who are going through the same kind of loss as you are now.
Cherish your memories and know she will never really be gone from you because you will carry her with you in your heart and in your memories. She helped shape who you are, so in a sense, lives on in you.
We are here for you. Talk to us whenever you wish. Sending you an understanding hug.
