I work with supplements for a living. Before you try meds try this. 
L-theanine 200mg 2x daily
st. Johns wart 3x daily
5htp 200mg 2x daily

natural and at. Johns wart has a very slight anti depressant effect but is an herb. It can possibly make you a little more subjective to sunlight but this is rare. Try it, it may make a big difference.
