For The Past Week I’ve Been Occasionally Feeling Nauseous, Different

For the past week I’ve been occasionally feeling nauseous, different things cause my nausea at different times. Sometimes certain songs I listen to give me headaches when they usually wouldn’t. Other times it’s smell and even what I see but not as much as smell and sound. The intensity of the nausea varies all the time. As far as I can remember, my diet has not changed recently and I’ve not changed any daily habits. As a sidenote I am currently taking 150 mg of Venlafaxine in the morning and 50 mg of quentiapine before I sleep. I am 17, of Asian descent, 115 lb, and roughly 5 feet and 3 inches tall. I plan on visiting a clinic or physician soon but until then I am desperate for advice. Thank you.
