I'm sorry for your loss, it's gotta be devastating to not even be able to say goodbye to a loved one.

As far as coping, as cliché as it sounds time heals all wounds. Meanwhile, focus and invest in yourself. Get a new hobby, pick up a new skill, go to school (unsure how old), meet new people, join a club, volunteer, and travel nationally. As mentioned above, there are handful of places you can travel to in our situation and still get that foreign feel. I've been to PR and I loved it.

When you're feeling down and depressed, remember Dory from Finding Nemo and just keep going, just keep going, just keep going...

You got this!
