Hello Yollie, thank you so much!!! :)

Answer

Hey Aya! This is pretty good :) I would possibly change 'I'm glad to see you again' to 'Nice to see you all again' as this is slightly more colloquial and natural. 
As it is spoken English you can also take out the 'and' before anytime. I would simple say 'so feel free to ask me anything, any time'.

Answer

nice
