yet, another morning sickness ruining a life

I'm in week 12 and my morning sickness hasn't lessened AT ALL!!!! I'm very upset and tired and just done with everything. I hate morning sickness so much and it's making me hate being pregnant!!! My doctor says that the morning sickness should start to go away by now, but it hasn't at all!!!! 
Who else is going through the same? 
I'm so tired of this that I'm crying as I'm writing this post
