Hi there ~
Please do not be anxious about the weight gain. It is a normal physiological process. Do not also concentrate on the numbers too much, even though they are important. It will just raise your anxiety
regarding the problem on hand, if there is one. I wonder if you have seen a nutritionist, since you so elaborately mention the kinds of meals you have been having. I understand that it might be a tough issue for you but checking with a nutritionist again might not be a bad idea. I would not attribute the issue to abortion
or the drastic weight loss
in 2011. I think it might be due to another unrelated issue in your life and you need to visit with a qualified psychologist
or counselor for the same. I also advise you to visit with a psychiatrist
qualified in eating disorders to be able to seek help for the issues you have been facing. I hope this helps.
Take care and have a lovely day!
