Dont worry sweetheart, you are just reacting normally as someone who is frustrated with their weight loss.
Congrats on fitting into your jeans..BUTTS rock! My husband recently paid me a compliment after years. He tried to pinch my butt and said..my god you have gone so firm! Needless to say that led to a getaway for some privacy!
I also have two jeans that I used to fit into for five years but cant right now. They are my motivation because my dream is to fit into them again eventually.
Make lots of soups and stock up on salad and veggies. Lentils are very cheap and make great soup. Throw in different veggies for variety.
Dont overthink your weight just think of how happy you want to be and what it will take to make you that way.
Good luck..keep going..The journey is only hard in the beginning, once you start moving, it will become a cruise.!!
