Losing weight, how to stop

Over the past year I’ve made a significant change in my life when I stopped drinking alcohol. Now, I’m 30, I’ve been thin my whole life, but around 2014 I started gaining weight, but not healthy weight. I’m 5’7”, typically I was around 125 in my early twenties, but around age 26 I started getting fat around my stomach (the worst-I looked pregnant), my boobs got big which was nice, but it also went to my face, my waist, and I just felt so uncomfortable. I ended up getting up to 142. It was nice having bigger boobs, but not being able to wear form fitting or tight clothes bc of the insecurity of my stomach just sucked. I was also at a really really low point in my life and drinking consumed me. Well, I’ve since stopped drinking, got a great job but over the past 9 months I’ve lost a significant amount of weight. I am now around 124lbs but I’m not happy and I feel like I keep losing weight. I stare and analyze pictures of myself from months past and it’s got me now feeling depressed and desperate for answers. I’m seeing my doctor next week for an overall wellness visit, I’m a healthy person, just want to know if anyone has any suggestions or have been through the same.
