I am so sorry you're feeling the stress and weight of this situation. (No, that's no pun intended.)
We cannot put life on hold in order to diet. Wouldn't it be nice? The world just waits quietly as we learn to eat healthier and end up trimmer and fitter and THEN we can deal with all the stress in a better way....
Alas... that doesn't happen. We have to learn to eat better and make healthier choices in ALL situations. The good. The bad. The frustrating. The raging. This journey isn't just about those weeks during the year when everything is normal (because is anything ever
really normal for anyone?). It's about learning
through the hardships. Finding out we
can do better for ourselves even when we're faced with obstacles.
You. Can. Do. This. We all have faith in you. That you can make better decisions and STOP the cycle.
One day at a time. Just like before.
A low-purine diet isn't -exactly- like becoming vegetarian, but I suggest finding a nutritionist to help you sort it out if possible.
And in the meantime if sticking to moreso-than-not vegetarian foods, there is a vegetarian area with all sorts of meal and recipe ideas.
Instead of focusing on what you can't eat... start making a list of the foods you like that you CAN eat. And incorporate those into the new meals you learn to make to help with your low-purine diet =)
One day at a time. Make the decision every day to be mindful to the best of your ability. You're stronger than you think.
