New Job, Nway from London, born 28.12.1974 Saturday 10:00 am.

Thanks very much in advance.
I so stressed in my current job. My manager is the bully character and because of her, one of my friend left from the job. Another colleague cried and getting mental. And my turn. I sat down with her for 3 times and discussed how I felt. She changed for 1 or 2 weeks and then back to mental again. She has roller coaster mood and behaved us according to her mood and never fulfill her demand. She wanted to us to come early work and stay late every day and blame always something.
I decided many times to leave the job. But I tried to survive in my current job because I would like to buy a flat as I don't own a house and rent are getting expensive. But I don't know when I will walk out if I can't control my mind.
My question is can I get the new job and when? And when can I get my own flat/house, please?
