Does this make me depressed or is this normal?

I'm usually a very happy person but it seems every couple weeks or so I just get this one day were I'm very depressd. And usually havethoughts of killing or cutting myself. But I've never cut myself although I almost did once but got too scared. I'm just worried because depression and bi-polor disease rin through my family. I did tel my brother once but he just said I was being over emotional. I'm sixteen

Don't worry, it's completely normal to have fluctuations in your mood, especially at that age! When I was 16, a lot of my friends were emotional cutters and my family also had a history of depression and various other medical disorders. I never cut, but I remember a time where I felt social pressures to do it... it seemed like if someone had a bad day, it was the "in" thing to do. Don't worry though, we grow up (and this happens way to quickly) and we look back and wonder to ourselves why we ever thought so negatively to begin with. Don't feel the need to grow up too quickly, but know that one day, being depressed as a teenager will a thing of the distant past and enjoy your youth while you have it :)
