That's a mighty impressive score! You obviously have awesome willpower. You face the same challenges as everyone else, but you have the focus to stick to your guns and hang tough, where others yield to temptation. You know that momentary pleasure fades, but being true to you - and the goals that you set for yourself - is way more rewarding in the long run.
Your willpower is in pretty good shape, all things considered. Sure, sometimes you give into your cravings, especially in times of stress. But you're usually strong enough to resist tempation when it counts, like not going after a friend's hot crush. Keep up the good work, keep building up your self-esteem, and you should make your way to most of your goals.
If it's bad for you, you'll usually end up doing it. It's not that you're self-destructive. No, you've just given up on the idea of having self-control. That's too bad, because always giving into your urges is probably messing up some of your bigger goals. You've got what it takes to be stronger - you just have to tap into it. Start by telling yourself you are strong enough to have better willpower. Believing that is the first step to real inner strength.
