What can i do to not procrastinate?

Set a schedule and abide by it. Say from 3 to 4 PM is homework time. When it is 3, TV off, phone off, computer off, everyone leaves you alone until it is 4 PM. Inform your family and friends that this is your homework time so no one bothers you. If you have a hard time concentrating that long, try shorter blocks, with short breaks between. Eventually you should be able to do your work in longer blocks. More importantly, set a schedule and stick to it. This is nothing more than disciplining yourself. Do it NOW.
