Starting Back at Square one....

Well, I am officially starting over. I have been trying to lose weight for a little while now and was down about 9 pounds. Then I started to get frustrated with my lack of progress over a few months so I started changing my calorie goal and macros to try to find something that worked well for me. Nothing seemed to be helping and I got discouraged and lost my motivation. I also hit a tough time emotionally and financially and kind of quit on myself. Now I am back to my starting weight and really wanting to succeed this time. I joined a gym last week and have purged my house of all of the unhealthy foods I had recently been accumulating. This is something I really want to accomplish. Anyone out there have any good advice or suggestions of how to stay on track, keep up the motivation, or anything I should be doing to help myself out to reach my goals? Any support and encouragement is always welcome. Thanks guys!
