Feeling that way occasionally as you get older might be a legit thing. (I felt that way in occasion, but it didn’t start until my 40sp. But all the time? That is excessive.

I would start keeping a health diary if I were you. Start writing down how you feel every day, nad note the time you are feeling poorly. You can just use a note taking app (or even a physical notebook), it doesn’t need to be a health app.

Also write down everything you eat or drink. You might find after a week or two that an obvious pattern emerges, and you can try changing your diet. But regardless, the next time you see the doctor you can discuss that history with them.

Don’t be afraid to get a second opinion on those lab results, also. Some doctors put an emphasis on different things. Another doctor might see a different pattern in the same results.

I hope you figure it out!
