A girls confession/needing support

Hello!
My name is Tonya Danner. I am wife and a mother to a beautiful baby girl.
My story starts before the pregnancy. Before my husband, i was in an abusive relationship not just physically but mentaly as well. He told me that if i weighed over 93 pounds, he would leave me. I wasnt allowed to go out in public in my pjs, nor was i allowed to leave with out make up. He monitored what i ate and made me feel ugly. I eventually left him after he almost broke my arm and when i did finally get out on my own, I ate whatever I wanted, when I wanted. I went up to 120 pounds. I looked normal! Then I met my husband. We married and soon after I became pregnant. I was so excited! I ate whatever she craved with in reason and I gained the normal amount of weight for pregnancy. When it came time to deliver, my daughters heart was unable to take natural birth so we went in for a c section. I was in a large amount of pain, mind you all of my stomach muscles have been cut at this point, I passed out during the process and my blood pressure dropped. I woke up in recover confused and dazed not realizing that they continued to pump me full of fluids. O left larger then I came in and had more strech marks than I could even imagine. I had them in places I didn't even realize you could get them! I went from feeling ugly to beautiful and then back to ugly all over again. My daughter hit a year and I still hadn't lost any weight after the pregnancy. Due to my terrible birth, I was unable to do much for six months. The weight stayed and I continued to tell myself that it was fine. It'd go away on its on in time. A year later, I decided to go to a weight loss clinic to receive some guidance and it is the best decision I could of made for myself! I now weigh 160lbs and I need to get back to my 120. My husband thinks that I do not need to lose weight even tho I am considered obese. He says I can do it on my own and that I don't need the pills the clinic gives me and says whatever he can to get me to stop going. It isn't about me so much as it is the money but he doesn't realize how much pain I am truly in. The extra weight has injured my back and kicked my arthritis into over drive. I can barely walk without my knees and ankles poping. I can't get on my hands to do push ups because my wrists can't hold my weight anymore. My back has a herniated disc and arthritis like no 22 year old has ever felt. I have a fatty, enlarged, and low functioning liver due to the extra weight and I have IBS. I never had any problems before and now I can't seem to have enough! I explained to him I needed to lose the weight and that my feelings should be taken into consideration and told him I would come up with the money for the clinic on my own. (I did a few odd jobs, I am a stay at home mom due to the cost of sitters which I would be basically working for nothing since it would go to them). Now I am going to the clinic and logging my food just like I am supposed to. I just wish I could of done this sooner! I would love to hear everyone's stories and how you are doing it. I would love advice!
I just gave away all the clothes that no longer fit, the clothes I think will but do not. The ones that I tried on every single day hoping something changed and when it didn't, I gave myself an anxiety attack full of tears. I have started a diet plan that was suggested for me. I am still unable to do hard workouts because of my medical issues because of this weight. I have lost mobility in certain areas of my body and I have tried physical therapy. I just took myself off of my hydrocodone for pain but I am still taking my muscle relaxers as needed. I would like to maybe do a detox and I would love some information on it or some personal experiences? Thank you for taking the time to read this!
