Needing some advice and support

Hello everyone, I've been struggling with my weight since I was a preschooler, despite the wonderful nutrition and serving sizes my health conscious mother gave me. At twelve I weighed 170 pounds and was constantly made fun of by my middle school gym coaches. I played soccer, was on the swim team for long distance swimming, played basketball, and played pickle ball throughout school. When I was 14 I went on a very strict diet and got my weight down to 155 pounds. My junior year of high school my weight spiraled out of control again and I've consistently gained weight. I'm in college to become a radiography technician, and I study very hard. I'm 19, soon to turn twenty, and at my highest weight. I weigh 214 pounds, whenever I look in the mirror or see a picture of myself I feel angry, ashamed, and extremely depressed. I become so depressed seeing pictures of myself that I'll cry my whole thirty minute drive home from my parent's house. I have no bigger fears than dying young, and at this pace I know it will happen. I want to travel and see the world, I don't want to get diabetes and die.

I have a firm understanding of portion control and I eat at most 1500 calories a day, most days I'm around the 1300 calorie mark. I also do a pio class on Tuesday evening for sixty minutes, and I walk 5 miles twice a week on my local greenway/hiking trail system. Last summer I had some blood work done for my thyroid, and my doctor put me on hypothyroid medicine, then sent me to an endocrinologist. My endocrinologist is a great man, very entertaining and he explains things thoroughly. After three months I became hyperthyroid and was ordered off of the medicine. He ordered a full hormone scan, during the blood drawing process I fainted and had a syncope (Seizure due to lack of blood and oxygen delivered to the brain), and it came back showing that my prolactin levels were high. Prolactin is a hormone that normally nonpregnant girls my age have in low numbers, around 25 to 30 mcgs, mine was over 200. I had an mri done on my Pituitary Gland, in which during the IV stick I fainted again, and am currently waiting until the 7th of October for the results. Prior to this month I had never fainted before, and blood work had never even caused me to be light headed. I'm beyond stressed about my weight, and am ashamed to say I would be happy to have a pituitary tumor because then I would have some sort explanation of why I can no longer control my weight.

I have a few questions now. Is there anything else I can do with my diet? Other than going on some heavily restrictive diet, I live in a small town and we have a limited selection of groceries and I'm not able to travel two hours to go to the nearest health food store every week, let alone every month. I also have a limited budget, I eating what I believe to be fairly healthy on only 60 dollars a week, mostly vegetables, eggs, fish, and milk. I have a soft spot for sweets, so I try to limit them to a lollipop, a fruit popsicle, or frozen grapes. Is there any other exercises I can do? I would love to go to the gym more, but it's 40 minutes away and my class schedule is hectic, so I chose to take my town's walking and hiking path twice a week. I've measured my walks and each walk I burn around 600 to 700 calories. I would try running, but even my walks give me severe right hip pain. What other things can I discuss with my endocrinologist and doctors that can get me on the right path? I feel miserable as a 19 year old, and I just want to be happy and feel pretty for once.

I'd like to thank you for reading this, and I am willing to accept any advice at all you can give me, as well as your words of support. Thank you again.
