I think you need to learn to be proud of yourself. Think how good you'll feel if you take your medicine every day while they're gone, and you can tell them when they get back! I understand wanting approval from others. But you need to find it within yourself, as well. You probably want to give up, because it feels comfortable to give up. It's familiar, what you're used to. So it won't feel comfortable to resist it, but it will get better, and you'll be better for it.
