My Abnormalities?

Well im currently 16 years old going into jr year. I wouldnt call my self so much as imature but, my family belives different. Ive been smoking weed for the past 4 months about 5-10 times a day. Ive been haveing some types of hallucinations while im not high, I dont sleep much anymore. Now today i heard my mom and step dad talking about me just pretty much bashing me saying i need to grow up and change. How do i actually change, i think im depressed or something wrong with me any suggestions?
