I hate my job

Since the new manager came my attitude towards work changed. Only four months into employment after two years of being unemployed I feel like this is the worst place I have ever been. She always has something to complain about, shout or bring you down. So far three people have resigned in the past 3 months and by the look of it more will still resign. We have tried talking to her about it but she can't just transform. The environment has become so toxic that I hate waking up in the mornings knowing how the day is going to be. I have tried applying for all types of jobs but I haven't been successful yet. I feel like resigning but I have a two year old and bills to take care of. I just want somewhere where their is peace of mind even if the pay is peanuts. What should I do.
