Hello everyone,

I'm ordinarily a happy-go-lucky guy that loves to laugh and live. I'm a 17 year old high school student that has several professional aspirations and has been meticulously planning for my future. I have no history of depression or any other form of mental illness,

but for the past week I've been experiencing major depression. The thing is that the depression comes and goes throughout the day. For a few hours I feel like my normal self and want to engage in activities, hang out with friends and family, etc. Then for a few hours I feel depressed and

This all started about two weeks ago. But for one week the depression would only last 30-45 minutes a day. This week however the depression can last hours. I've never experienced anything like this. I don't I have bipolar disorder because I haven't experienced any restlessness or racing thoughts.

Here is some information

-I live in Southern California and it is currently foggy and raining.
-I have been consistently experiencing nausea in the early mornings.
-I feel tired sometimes
-The depression comes on randomly and can last for 30 minutes to 4 hours before it goes away
-I have never become aggressive or impulsive, my mood swings consist of depression and my normal self
-I have been depressed in both the sunlight and in the fog, however it is the changing of the season in SoCal and it has been particularly rainy.

I just want to know if mood swings occur with SAD...

I really hope I don't have to go on medications because I feel like it's going to **** up my brain. Please don't take offense, I just want to let out my feelings.

SHOULD I SEE A DOCTOR
