Weight loss while being sick

I’m 31 years old, 5’1“, and I’ve gained some weight over the past few months. I’m now around 122 lbs and feel comfortable with 115 lbs.

Normally, I’ve been going to the gym 3-4 times a week for the past years. I actually wanted to lose weight for spring, but I’ve had a sinus infection for 4 weeks now. Before that, I was traveling for a month, so I haven’t worked out for two months.

I know I’m at a normal weight, but I honestly feel terrible about myself right now. For the past two weeks I’ve been eating around 1400 kcal, but I feel like without exercise that might still be too much. At the same time, I don’t have the energy to eat less, and I feel like my illness is never getting better and the break from working out will last even longer.

I’m kind of desperate right now because I’m scared of summer, scared I won’t get healthy. I am angry because of my height. Life would be so much easier if I was taller. Does anybody have some recommendations or thoughts for me?
