Narrative:

On approach to clt; approach control told me I could continue the approach but probably would not get in as there was a 50 kt wind shift at 200 ft. On final well before my minimums (restricted captain) I elected to go around; I was flying and the missed approach vectors put me back into more turbulent weather; I was basically hanging on to the aircraft; go around initially was slowly accomplished; with the wind shear I think I came close to a flap over speed; but not completely sure; I had just enough fuel to divert to ZZZ; after landing in ZZZ I felt 'rattled' and still in the yellow; I elected to overnight there. The rub comes in when I told [dispatch] that it was not safe for me as a restricted captain with less than 30 hours on the equipment to fly back into the aforementioned weather in clt. [Dispatch] said they would give me a missed trip; I then said I was fatigued to stop the show. Nothing shows anything about being fatigued on my [record]; only shows that I was reassigned. I thought in the best interest of safety I should stop at ZZZ for the evening; not sure why [dispatch] could not understand this; they certainly need to. Resumed rest of trip the next day and got the folks into charlotte; then dead headed home. Weather is why it occurred and my own lack of time on the 737. The conditions were very challenging for any crew especially for a restricted captain and fairly new first officer. We did the best we could do and as a not new captain I do know when to say no! Don't try to push a crew into a situation that in the captain's judgment is not safe.
