I think that a lot of us are in the same boat the whole world over...
Each day I "try" and get into my model room and do something, sometimes that something is putting a couple of things away or just sitting on my model chair for a few minutes. If I am lucky I'll do a bit of sanding or glue a couple of bits together then sometimes I'll be able to get into it for a couple of hours.
Here in New Zealand our prime minister has suggested that we all remember "to be kind to one another" as we are all in this together. I suggest to go one step further, that is to remember to be kind to yourself too!. Don't beat yourself up just because you have lost your MoJo, a creative hobby like ours requires the right mindset and that will come back in time.
For now try and focus on what "we" can do to stop the spread, STAY HOME, look out for friends & neighbours who might need help, be kind and once it is safe to do so, then we can look at picking up the pieces.
