Hi aasshhlleeyy
You and I started almost exactly the same weight. I have felt exactly like you do and one thing I tell myself that seems to help is to "trust the process." If you do what needs to be done consistently the weight will keep coming off. Even my doctor told me "No one loses weight on a straight downward line. Everyone's weight loss goes up and down as life happens but as long as the long term trend is down, that is what is important"
Also, I am not sure what kind of workout you did but I thought I'd share my experience with you. EVERY TIME I work out with weights with my trainer I will gain around 2-3 pounds. Like someone above said, it can be water weight from your body repairing your muscles. I went on a 5 hour hike with my husband the other day during TOM and gained 6 pounds. SIX pounds lol!!! But I know the hard workout I gave my body was worth the increase in my fitness level.
Maybe don't go on the scale for a week if you can hide it away from yourself
My trainer told me to do this and once I stopped stressing about it my body finally let go of 4 pounds in one week.
Hang in there girl!! It will all be worth it
