New to MFP, need some friends

New to MFP and not sure how to add friends. Could use some motivation from people like me
I am 5'7 and I started out about 3 weeks ago at 222 and so far have lost 7lbs. I have stayed under my calorie goal most days, but am still not eating "healthy". I have been walking at least a couple miles almost every day for the past week or so. I also just recently found out I have hypothyroidism and am taking levothyroxine. Any advice or tips welcome! Add me if u'd like.
