Maybe you should try embracing the hunger. I'm on the opposite side of the spectrum, too skinny. It was very difficult for me to gain muscle mass for the longest time. Eventually I came to enjoy the feeling of working out for the muscle soreness it caused. I still do not enjoy working out after 10 years, but I associate soreness with muscle gain and fitness, and so I enjoy it. If you are able to convince yourself that hunger is actually the feeling of yourself losing weight, it might be easier to embrace. Hunger can be torturous but it isn't dangerous.
