<human>: Okay, I need help! I've never had an issue with my weight. I've never had to count calories and the only time I worked out was when I felt like it (which wasn't often).

I've obviously noticed some weight gain but I was trying to not think about it too much. 3 months ago I started taking a new medication for anxiety. It works great but the down side is that it GREATLY increases my appetite. Seriously, I'm hungry 24/7. Today, I went to get a check up and I weighed in at 137lbs. three months ago I was 115lbs. I realize 137lbs isn't necessarily heavy but I'm only 4'11 in height so even an extra 5lbs makes a noticeable difference. 

So, I need help please! What's the best way to get to a healthy weight? I've always heard the best way is to simply eat healthy and burn more calories than you consume, is that true? Also, how can I attempt to curb my appetite? Any help or advice would really be appreciated! Seeing my weight on a scale this morning was a wake up call and I desperately want to get it under control before it gets any worse.

Can you condense the text into a few key points?
