<human>: So for a while now I've had a serious lack of willpower when it comes to doing what's good for me. At first it was just being too lazy to work out and eat healthy, and sometimes be lax about school, but recently it's become a REALLY bad problem. I'm eating out way too much, spending too much money on food and not eating healthily, I'm really behind on schoolwork because I get distracted easily. I'm afraid this lack of willpower may start seeping in and start ruining friendships and relationships (if it hasn't already). 

How do I go about changing this? Is it just as simple as telling myself to get it together and start being an adult?

Give me a shortened version of the text
<bot>: don't have willpower when it comes to things like spending money or being responsible, how do I change this or do I just have to start being an adult?
