Does Zoloft 200mg And Trazodone Cause Stress And Anxiety?

I think I may have stress exhaustion. My hands tremble almost constantly, and the inside of my arms and sometimes my chest does the same. I am taking 200mgs of Zoloft mornings, and 50 mg of Trazodone at bedtime. I have never take Trazodone. I have never taken any more than 50mgs of Zoloft.I am very nervous, and anxious; way more than usual, and I might cry at the drop of a fly! Do you think the meds. could cause these manifestation and and the new intensity of anxiety? It is with me every day all day! Thank you for your advise.
