First off, HUGS. I know how frustrating this must be for you. I stress over every little pound (I know that I should not). I'm sure that you have heard time and time again protein and water BUT it's soo true and it works. Are you eating protein first at EVERY meal and drinking plain ole water when not eating? If not, please give this a try. Protein should make up at least 80% of what you eat and ideally water should make up 95% of what you drink. I know that some do tea, coffee, shakes, etc. and that's fine BUT with your sitution I would focus on drinking jus****er.
Oh honey I hope that the scale get's moving for you soon and puts you in reach of your weight loss goal.
First, I am so sorry you are struggling. Your doc will be able to help you determine if you have a mechanical issue or if it's something else when you see him.
I can understand how discouraged you must be, so I went and dug up the following link to THE BEST post I have ever seen on evaluating and breaking a stall. The author, Pam T., looks helps you look at your current stall/plateau from every conceivable angle. I used this all the time when I was in my active weight loss phase and still look at it if I feel like I am stuck or gaining for some unknown reason. It is an awesome tool:
Maybe if you have a look, something will catch your eye that will help you get started on addressing whatever's up (assuming it's not mechanical of course).
Good luck to you. Many have stalled for 2 or 3 months farther out and then went on to lose more. I know that is what happened to me last summer. Thought I was done losing but wanted to make double sure there wasn't anything more I could do so went through this list, made the appropriate changes, and ended up losing another 25 pounds.
Hang in there. You are doing the right thing by addressing it now while you are simply not losing, but not actively gaining either.
