Close to 2 years Post op VSG...NOW WHAT?

Hello all my fellow palers. I am a VSG pt. I had my surgery 2016 May. My initial goal was to get to 170lbs. I began at 280. I am now 158-160. I know what you're going to say...but you've reached goal. Yes this is true. I have set a new goal however and that is to get to at least 148. I am getting married in 2019 and I want to not only loose this last 12 pounds, but I also want to tone up as much of my abdominal area as possible.(I really don't want to wear a gurtile. They are not the most comfortable. I know beauty is pain however comfort is more important to me.)
I need help setting a routine for the gym. I go to my gym at my job 5 days a week at 40 minutes each day ( I go during my lunch break at work) and mostly do elliptical and treadmill and stairs. I do the occasional reps on the weight machine but that's basically it. I have a membership at Planet fitness and plan to go there on the weekends and some days I have off. I work Monday through Friday 8am to 7pm in a hospital, so you know my life is pretty hectic to say the least.
I have to be open with you all and let you know that I do suffer from anxiety. I have to motivation to go but the thought of being there by myself scares me. I live in an area that finding parking is like finding the holy grail. Once you have a spot, you better not move until the next day. It takes me close to 20 minutes just to end up finding parking close to 6 blocks or more away from my apartment. I purchased a bike to ride to the gym but the weather has been terrible. I get scared riding in the rain let alone snow or at night ( NY drivers are not the most courteous on the road).
So back to me wanting to loose the 12 pounds. I need help. Any pointers to jump my metabolism? Food, snacks gym routine? I am finding that I am getting hungry faster. This app has given me a breakdown of what my goals for each are but still I am finding myself grazing. Any help would be appreciated.
