Advice on frequent nosebleeds?

Hi, everyone! I'm 16M and I weigh approx. 200lbs and I am 5'6". The only prescription medication I take is fluoxetine for OCD and depression, along with a vitamin D supplement recommended by my doctor. I've never smoked or done any substances either. Recently (in the past year or so) I started getting nosebleeds frequently, but it's gotten to the point where I have nosebleeds almost every day now. I've tried a humidifier and nasal spray, but none of these attempts have worked. Usually the nosebleeds are heavy, but short and only last for a few minutes. Occasionally they will be heavy and last for up to 20, though. My nosebleeds are usually followed by dizziness and extreme fatigue, to the point where I feel so tired that I can't stay awake at school. It almost feels like someone is simultaneously pushing my eyes into my skull pressing my eyelids down. I haven't been to the doctor about it yet, but I wanted to see what anyone else thought about this. Thanks!
