All day nausea... When does it end?!

La

I'm at 11+2 and my nausea shows no signs of stopping or even tapering off. I haven't vomited, but all day I walk around dry heaving with a bowl handy nearby just in case. I hate this and feel so guilty for feeling this way but I am so done with the nausea, the fatigue, the acne, the constant urge to eat even though it makes my nausea worse... will it really stop in the third trimester?
