Gosh, POETICSIREN3080 !!
I'm so sorry to hear that you were in such a horrible accident. I know that you're unhappy that you've gained 10 pounds, but you can't worry about that right now. You've got to work on healing your body. Talk to your doctor. They might not want you trying to cut calories. You need those calories to help your body recover.
For now, if you want to do something good for your body, concentrate on eating healthy foods that nourish your body. Don't worry about cutting calories. Keep eating as many healthy and wholesome foods as you can. Plenty of fresh fruit and veggies. Lots of whole grains. Remember, weight loss is nothing more than a byproduct of a healthy lifestyle. So, if you're eating right, the weight really will come off on its own. but, once again, don't worry about that.
Talk to your doctor. Like I said, they might not want you cutting calories while your body is still in recovery. Also, some of that weight gain may not be fat. It may be water retention because of the medications you're on. Many medications can cause a person to gain weight even though they've been eating right. I can't tell you how many women I know who packed on weight because they changed their birth control.
Take things one day at a time.
Get well soon !!
