Job change in July?

I'm a woman born in 11/29/1978. I've been through so much problems at my job since October 2013. Especially last few weeks-from june 8-through june 20, 2015. I tried to ask to transfer me back to my previous job but the big boss say NO. Anyway, I want to know when can I change job? July? I hope to move back to my job asap. Thanks in advance for prediction!
