Welcome to the forum. Your post resonated with me today as I was talking to my friend in Canada who also has two hospitality jobs which have gone into hibernation and she also was expressing concern for her future and had some big questions as you describe about the hospitality and tourism industry, the economy, will it be the same again? AND today my brother just got a kitten (this was planned before the pandemic) and says it is blessing to have a new pet in the house.
As far as socialising during this time, you are already doing it to some degree. You are online, you are on this forum and posting. These are steps that not everyone is comfortable doing so well done for being here and reaching out in the public space.
So many of us have these big questions and it is truly an unpredictable space, even for our global leaders. Taking things slowly and not feeling pressured to know everything is important for our own mental health.
Allowing time to question the unknown is important but putting some structure around that time can help us to stay in a more practical space. In some therapy structures, you can even name it and call it 'worrytime' or something of the like.
For example, you could spend an hour in the morning and an hour in the evening worrying about the things you cannot control, but then put those worries in a box on a shelf and focus on some of things you can control such as time with your kitten, trying an online course or class, Facetiming others, using the BB forum etc.
The forum is a safe place to reach out and I hope you find many outlets across the different areas. You will see that there is social zone where many people connect and do games and other activities.
You are not alone.
