Dear Del.
I know it's hard, especially the first few weeks. But you must remember you've entered a world wholly separate from your parents. Of course I wrote to my mother and father as much as I could, but they never understood a thing I was talking about. I was fortunate to have Mr. and Mother Weasley.
Your parents love you Daffodil and always will no matter what. They are adjusting the same as you. Continue to write to them, and let them know despite all the changes going on you still love them.
Don't expect them to understand your world, just know they are trying. I know you're taking in a lot right now, and so are they.
I still write to Mum and Dad. While they are proud of me, and happy for us all, (They positively adore Ron) I see in their eyes that they are at a complete loss of what to say. If you wish, I can send along the address to give to your parents. It might help your mother and father bridge the gap. And I know my parents would like someone else to talk about it to as well.
You're making a slow transition. Not just from Girl to Woman but also into the wizarding world.
I advise you to take it in your own pace and let your cousins and us support you. We love you dearly and want you to be happy and comfortable. I'm here anytime you need to talk.
Love from
Hermione.
