I think I have depression..?

I think I have depression caused by iron deficiency ( I know I have iron deficiency ). I keep snapping at my boyfriend for little stupid things and then I end up breaking down in tears afterwards, I hardly feel any emotion anymore and sometimes I just want to die. I used to be energetic and happy till I became iron deficient.. I can't see a doctor. My dad simply can't take me. He's too busy. My mom won't take me because she simply doesn't want to... I've asked her before and she yelled at me for the whole rest of the day... but I'm so sick of feeling like this. And I hate to put my boyfriend through this.. I don't even feel interested in anything anymore. I feel like I don't have any options.
