Advice

Hi,Sophia
I'm so glad to recive your e-mail to let me know what is on your mind.
Obviously, Denise is in trouble now. Yes, you need to speak to her. If you don't, the situation wcould be/get worse again. I think you it would be better to understand her first, and then you can do something [for fun] with her for fun.  It's may be able to distract her from the worste of it thing of her. When she feels better, it's time to speak to her.
I hope my advice has been to helpful.

Hi,Sophia
I'm so glad to receive your e-mail and to let me know what is on your mind.
Obviously, Denise is in trouble now. Yes, you need to speak to her. If you don't, the situation would get (I think it is better to use ''get'' instead of ''be''here) worse again. I think you would better understand her first, and then you can do something for fun with her. This may be able to wash the worst things away of her. When she ''gets'' or ''feels'' just add ''s''better, it's time to speak to her.
I hope my advice has been helpful. ''no to before helpful but you can say has been helpful to you''
