The best lighting would be three point lighting. You can honestly pick up a few LED worklights and set them up around your room. Wax paper can be used to diffuse the light (which I recommend) to make it look softer. You want a key light which is next to your camera (I can't remember if it is to the right or left, I need to look at my school notes.) Opposite of that, and hidden from the shot, a back light to make you POP from the background. If needed you can add a fill light, or a reflector to make the lighting on your face even. I recommend googling three point lighting, that is going to really make you pop in your room
