Im always hungry. Why? Related to thyroid?

I'm constantly hungry and never feel satisfied. I can't remember the last time I felt full. It wasn't always that way. I was skinny as can be until some time around puberty and then over the years I eventually got up to 300 pounds by age 21. I recently was able to lose 115 pounds over a year and a half. I quit diet and exercise and returned to a somewhat normal diet about 6 months ago and have since gained back nearly 40 pounds. I just got TSH checked and it appeared normal 1.24. I've been reading about hashimoto disease and finding a lot of common symptoms mainly the psychological ones (anxiety, mild depression, agitation, paranoia, delusion). Does Hashimoto's sound likely?
