Stress eating?

I’ve put on some weight over the last few months. I understand why – lots of eating of junk food – oreos, grapes, hotdogs, chips, and so on. I eat a couple of times a day – sometimes three times – but its the quality and quantity of what I eat. I try to get more than 8,000 steps a day and often I can get 13,000 to 15,000 steps at work and after work. It isn’t enough to counteract my terrible eating habits. I started back to CrossFit a couple of weeks ago and had to stop because I overdid it with the boxes at work and then this week I stupidly pulled the ballot box out of my car – it was way too heavy for me and I did it before I thought. Now my shoulder is aching and unhappy – I had rotator cuff surgery on it two and a half years ago and its been doing great until now. I feel like an idiot – I definitely do not want to hurt my shoulder again but I feel like I really injured it this time. It does not help me plan a new diet possibility. I need to figure out a way to motivate myself to lose weight and to give my heart some exercise. I’m planning on doing tabata with Angel Squirrell at the Fitness Center this coming week. I’ll probably pass out on day one. lol
