29 years, want to lose 30 or so pounds

Hi I just joined less than a week ago. I'm 29 years old 5'4 and 150(ish) pounds. Looking to lose at least 30 pounds.

I used to be slim and fit but a combination of being in a car accident and getting onto meds that cause weight gain led me to gain 75 pounds in one year. I've lost some of those pounds but have been sitting at 150 for 2 years. Now I'm ready to really lose the rest of the weight. I'm serious this time! I also have a mental illness which is one of my biggest challenges. My main exercise comes from going for walks and hula hooping, I'm also making an effort to go the gym more often.

If you can relate on any of those points (or even if you don't) you are welcome to add me I have only a couple of friends and would love to have some more.
