HELP WITH BESTIE!!!!

This one is my question to all the girls here i have a bestie ive known her for over 6 years now she means alot to me is close with my parents and my family in general aswell but on sunday night i kinda made a very big blunder and now she is angry on me and isnt talking to me luckily im not blocked by her i just need to know what i can do for her to show that im actually sorry and this wont happen again and also just to add she has very strict parents who hate her talking to any boys so me meeting is totally out of question as it will raise issues for both if us. so girls plss give me advice on what i can do for her to show that im sorry that i care for her aswell. Edit: since y'all are asking for blunders she wanted me to console her but I didn't see the messages as I was gaming with boys and when I did see them I was unable to properly console her
