I'm starting to feel like this too, and at the beginning of lockdown of it I was one of the buoyant, optimistic ones.
I'm self employed and my work has dried up to nothing. At the start of it - in April I was paid some outstanding invoices and got two lucrative jobs in, so I was mistakenly confident I would be just fine for work through lockdown
How wrong was I? In early May I earned £165 and nothing since and absolutely nothing on the horizon. The self-employed grant was an absolutely godsend, but of course it's one payment and the bills keep on coming, so I am having to watch every penny and I am literally counting down the days until we get the next self-employed grant which won't be until mid August. Two months away!
I was also motivated to keep myself busy in other ways, catching up with jobs around the house, garden, cleaning etc .. but lately I can hardly motivate myself to do anything. I was going for walks or bike rides every day - now I can't be arsed. It just seems so pointless walking or biking around aimlessly, going nowhere with no purpose. I'd love to paint all my fence panels, but I'm terrified to spend money on the paint.
I'm tired and exhausted doing nothing - sleeping 9, 10 hours a night and waking up with no energy or motivation. The boredom can be mind numbing and there's no more books, films, programmes, crosswords, puzzles, quizzes .. that can distract me. I'm bored of it all. I'll have days when I have spurts of activity but then other days when I don't even get out of my pyjamas.
I'm hoping my business will come back, my clients will return but I don't know that. This could be it for me after 27 years of continuous self-employment. The future is all so uncertain and though I try not to worry I can't help it.
On the plus side, although I'm a single mother I do have both (young adult) children still at home, so I have the company of young people and both have secure jobs (currently working from home) and both pay me regular keep so I'm not completely without income, albeit barely enough to scrape by.
I also have a garden which has given me a lot of pleasure and I've been able to get it looking really nice, but of course, when the weather's shit - like today - it's not much help.
I can feel myself sinking and then I'll have a day when I get my arse into gear and do loads - exercise, walk, clean, do a DIY project, writing or doing something creative for myself,, but invariably the next day I'm back 'down' again. The up days are becoming less and the down days are becoming more, even though I'm fighting against it for all I'm worth.
Life just seems so pointless without purpose and it's hard to create purpose out of nothing.
