I just want to say this on the subject of "mental hardship" as a result of social isolation:
Humans are capable of a LOT more hardship than they think. The human spirit, instinct to survive, and ability to adapt is incredible.
Americans, as a society, are generally spoiled by our privilege. We haven't had a war on our soil in over 150 years. Many people alive now have never experienced a real, true hardship.
We are in the early days of this "new normal" and people are understandably wringing their hands and feeling like they are starting to go crazy because everything they took for granted is now in jeopardy. This happens to millions of people every year in this world. It's just now happening to us.
We can handle this. All of us can. You are stronger than you think you are. You will adapt to this situation and realize that you are capable of being okay even without all the comforts you had before (to include close contact with loved ones).
I am a military spouse and not to toot my own horn or anything, but this has basically been our life over the last 21 years. Frequent separations due to training, field exercises, deployments, etc. For over 5 cumulative years, my husband has been separated from us, many times in a war zone where we had to worry every day if he was going to live or die.
I haven't seen my husband since Dec 31. He has been stationed in Japan since last July, without us. He is alone there. He also suffers from depression and PTSD, but he's still managing, even under increased restrictions (he's basically under lockdown too now). We won't see him again until he comes home for good mid summer. It stinks, but it is what it is. Its basically another deployment at this point. #6 for us.
It IS possible to replace physical contact with virtual contact and stay safe and happy and maintain long term relationships. Military families in America have been doing this for literally over a hundred years.
You can do it too.
The great thing is, we have technology that we didn't have even 10 years ago. I mean, 12 years ago, our video calls to my husband in Afghanistan were these terrible quality, glitchy, time delayed static snowstorms. We have it good these days. Take advantage of that tech and encourage your loved ones to do so as well.
