Hi! Sorta new here!

Hello! So I joined MFP a few years ago and sort of got discouraged so I stopped using it. However I find myself googling and reading posts from others all the time so I figured I'd post and see if anyone has any great advice. I go through ups and downs emotionally just cause I really don't know what is going on with me. I'll try to keep this short. My whole life I've been pretty regular but when I got into high school and college I was especially in good shape. I was a competitive cheerleader and was 5'2" and about 118 lbs. went to college and stayed thin probably cause I continued to work out and consumed all my calories through alcoholic drinks lol. I've always been lucky. I are mcdonalds del taco you name it whatever I wanted my whole life and never gained. Let's fast forward to 24 years old (meanwhile at age 20 I grew to 5'6"). I had been on the depo shot birth control since I was 16, another thing that kept me skinny which No one could believe cause it's usually the opposite. After being on it for 8 years the doctors took me off it although I begged them not to. 1. Because I have too much estrogen and have endometriosis which landed me in the ER every month in pain which is why I got on the BC to begin with to get rid of my cycle. Well, within 6 months of getting of the shot, my estrogen levels went insane and although exercising SEVEN days a week, I shot up to 160. Additionally I found out I got hashimotos. I begged them to put me back on the depo thinking it would reverse this but nope, one year later I am now 157. I exercise 5-6 days a week two hours or more a day (cardio lots of weight lifting, all paleo diet except good carbs sometimes before a hardcore workout) and three lbs lost. I can't even begin to tell you how depressing it is to work so hard and feel so tired and fatigued and have no results. And I'm not just going by lbs, inches lost and pant sizes have not changed either. I think it's really upsetting me mainly because I went through life being a size 2 and at 26 I feel gross and just weird in my own body. My chest size went from an A to a C which bothers me the most-- I've always been very happy to be flat chested and can't even wear cute shirts anymore. I'm being tested monthly for thyroid because my doctors have no idea what's wrong and I'm about to go get liposuction and a breast reduction if things don't change soon. Sorry for being a downer but I thought there might be others out there that can help and support and understand what it's like. this sounds so vein but it's more that I feel sick when I see myself and just being in my own skin. could use some encouragement, a "don't give up!" Attitude and hope that others out there understand having a mystery medical condition that won't let you lose any weight !
