Oh, I hope your dad gets better soo with all myheart. I send you all my good energies from Venezuela and I will ask God to help your dad.
I know it will turn out well, and your dad will be with you at home as soon as possible.
You just have to give him a lot of love to forget the pain he feels, and let him know that you are there for him, I'm sure your love is all he needs. If you want to talk or vent, I'm here to read you! You're not alone.
