You must take care of your family first Vito.
Your parents do not need added stress right now.
You are young. You have plenty of time for another run.
We will be standing behind you when the time is right.
Words of wisdom bullcat.
People that leave threats like this are cowards. Though yes, you should definetly file a police report and SHOW them the evidence. I am sure you can well take care of yourself but I understand family concerns. Having two teenage children has actually held me back from going as far as I would like to go in the war on islam and especially in the political arena here.
Yes, you are very young. G-d works in mysterious ways, maybe you will be much more needed at a future time than now. If you continue to see this in your future, keep learning, so when the time is right you will be prepared.
I will also be behind you when you are ready, hopefully I will still be around as you are only a few years older than my own kids.
Still praying for your dad, hope things are improving.
Sometimes doing what you must do is a lot harder than doing what you think you should do.
I am sure we all here understand and support you 100%.
