They did another layoff at work

My manager called me the day before and told me they could no longer pay me the raise they gave me for my current position and would need to cut that position and bring me back to just doing the other two jobs, but.... They would like me to still do the third job regardless of the annual pay cut. Oh and all bonus income for us will be cut in half. It was a gut punch and I didn't feel like I had a choice because the alternative if I said no was I'd have no job today. I have many colleagues I've worked with over the years who are currently laid off and I know finding work in my career field right now is brutal. I need my job, they know that. I am barely surviving now and I'll be taking a massive pay decrease now. I don't really know what to feel right now. I guess I just feel numb. I worked so hard for so many years to get to where I am in my career and all to be demoted for something that is no fault of my own. I will just keep working until there is no more work and try to figure out how to make ends meet. I've survived before I will survive this
