How do I stop Skipping School?

I've always had a little problem with wanting to go to school but ever since we moved and I've been getting up and going to school on my own its like I never go anymore. Just this week I only went twice! I keep having to come up with excuses with my family that are landing me in the clinic now because they think I'm sick. I know that telling them the truth does nothing because I've tried that already and I honestly do understand how important school is. I've never come so close to failing my cles before and yet I'm still not going! I understand that its all about "will power" but I feel like I've tried everything and nothing is working. No matter how much I try I just can't seem to actually go to school... what should I do?
