Help...........

Hello, I am from class XI (science stream) And I have an addiction of instagram. On usual days i spend like 4-5 hrs on ig (for a nilofer 4-5 hrs might not seem much). Apart from it I also like gaming too but I do that moderately. I have my finals from MARCH 1ST and i have like half of physics to cover and revise chemistry organic part and thermodynamics part completely cuz I have forgotten most of the things. I also shat in recent unit test of school. Can anyone help me get over this addiction??(Tried deleting but keep getting back to it) Any advice will be appreciated
