I have dreadful periods and pmt that causes chaos monthly, affecting family life..will a hysterectomy cure me?

You need to go and see a gynecologist as soon as possible. Yes a hysterectomy would fix your problem but until a doctor does other things first you probably won't be able to get one. There are quite a few things that can be done, medicines for example. There is also a procedure where they install a "balloon" to help with the periods and the bleeding. Talk to your doctor and see what he or she recommends.
