Anything in my chart related to this time of year?

Can someone look at my chart and tell me why I get depressed and irritable during the fall and winter months? I've been told I have seasonal affective disorder however I've seen numerous members talk about how the different planets passing through different signs tend to have an effect on us.

I've had numerous friends say I disappear off the face of the planet from late August well into February and keep minimal contact with them. I also notice I am drained of mental and physical energy on stormy and cloudy days.

Ignore that link for a sec. Updating in a few.

Pisces.

Must have entered something wrong.

Found a transit chart from the same website.. apparently this time of year Saturn is Opposite the Sun which has negative effects.

Enter 18 May 1988 and it'll come up with my transit info.
