Shining - sorry about your job. really, but the Good thing(s) are
Your current boss sounds like a jerk- find a job with a nicer boss.
You do not like project type work of busy/slack (some thrive on it) so a job where you are consistently busy may suit you better.
Since it is all change this may be the time for a nicer job.
Where I live you cannot get rid of a worker simply to replace them with someone cheaper. Dismissal is more complicated than many bosses realise these days, especially bullies, who tend to be know it alls. I would check out your rights here. You do not have to stand on them but it might be good to remind your boss even if it is to buy more time.
If this helps, some years back, my eldest son did not like what was going on in his law firm and he said so (he did a consult with another firm and they confirmed that he was correct) He told his firm he could not do as they asked, and they let him go with a good reference and three months full pay. He got another job with a better firm in a better location and is now on partner track. Just so you know it can be positive. Oh and his wife was ill at the time, so it was a brave thing to do.
