Swollen and itchy clit.

Hi there. I'm seventeen years old, and I live with my dad and younger sister. Due to some issues with my mother, I no longer talk to her. I currently have no motherly figure ever since my grandma had passed away last year. I've had my period for a few years now, and its pretty normal. Last week, I got it. Slowly my clit as well as the skin around it began to swell, and itch. It's obviously irritated but I don't now why. I've used the same brand for years, so I don't know what it is. I haven't had sex, and I do clean down there. I've had the burning/swelling for about a week or two now. Its hard to sit still, because its so itchy. When I sit, it hurts. When I stand, it hurts. It also gets really swore and I have trouble sleeping being of it. I don't want to go to the doctor, it would be embarrassing to ask my dad that! I doubt its nothing too serious.. For example, I'm almost positive it isn't a yeast infection. Is there anything I can do to help the swelling and itching go away? Warm baths help, but I can't stay in there forever. If it doesn't go away with another few weeks I'll go to the doctor. For now, what should I try to do?
