Should I continue to work here?

It has been close to 5 years that i have been working at this company, the work culture is so bad, overworked, work for more than 12 hours every day, even working on all Sunday’s, it has been 5 years almost and i have not got a chance to take a holiday, don’t get to take my wide out, boss messages about work without even looking at the day or time, micro management is killing it, should i continue to work? I don’t have another job offer in hand but i am completely burned out.
