Sorry to hear about your situation - what everyone said: focus on your health first, everything else should come second.
Also, please don't take random advice about diet fads from an internet forum. Many of the health problems you describe, including the weight gain can in fact be caused by the hypothyroidism and you won't fix it by trying random diets or even by various gym regimes (although regular exercise and eating healthily probably doesn't hurt of course).
As someone whose (almost) all family members have thyroid disfunctions, I know it is a problematic disease, but entirely treatable/managable in 2014 in most cases.
I don't know where you happen to be in, but both in my original country (Romania) and my current country (western EU) it has cheap or entirely covered treatments.
In summary, one way to go is via medication: try to find the right mix of medicine, and monitor the thyroid indicators regularly - this is a hit-and-miss approach because the thyroid function has a "lag" - you change the dosage when you feel it necessary, but then it is usually too late as it swings from hypo to hyper or vice versa. In practice it is almost impossible to find the right dosage on long term and you keep swinging from hypo (brainfog, weight-gain, etc) to hyper (weight-loss, random heartbeat, sweating, etc) and back. Especially the hyper condition is harmful on long term, and some of the medication is also harmful.
Which brings me to the other approach preferred in some countries and in many cases: removal (partial or full) of the gland and/or radioactive iodine applied to it. After this, you need to take pills, but generally the situation is much more managable and the outlook better.
I just wrote this up based on what I know from family members, but please do your own research, get proper treatment and a predictable income (as others suggested, ideally in form of a salary in a country with good healthcare). Take care!
Adding as a reply as I couldn't modify it: obvious disclaimer - don't take medical advice from the internet, but try to visit a specialist doctor. The above two ways to go were the choice some of my family members had to make. Also don't experiment with medication on your own, but follow the prescriptions - however, the doctors will also modify the dosage mostly based on how you say you feel and the indicators from blood.
