We all experience life differently. We all have different genetic make ups, physiology, diet, exercise and deficiencies and/or excesses (known and unknown). We all manage our AI and other issues differently. As a result of all of these differences and many more, we all will experience life very differently from others. At different points in our lives, we may experience similar situations differently. For example, I used to be a puker. Now, I'm not.
When you experience things, good or bad, write it down. Have proof of the things that are happening in your body. No offence, you probably don't have a photographic memory (OK, you over there, you might, most of us do not). Written proof of your experience is evidence of how you feel and when you felt that way. We all need this information to believe in ourselves and to see patterns. I digress!
Even if you don't write things down so that you can see concrete patterns (or total chaos), if you have symptoms, you have symptoms. Believe it. Do not let a friend, relative or medical professional tell you that it's not possible for you to feel something. Just because people might tell you that something is not possible, it doesn't make your experience less valid. Yes, you can be fatigued on 20 mg of hydrocortisone. Your thyroid numbers might be "normal" (according to unresearched medical professional who is ignoring all of your obvious symptoms). If you are tired, you are tired. If you have a doctor invalidate your experience, get a new doctor IMMEDIATELY. If friends and family tell you that you're not tired or what you are experiencing is not actually happening, I don't know what to tell you but personally, I wouldn't share information with them any more because they are jerks. Friends, family and medical professionals should believe in you and your experience. They should listen and feel empathy. They should help you find solutions to your issues.
If you don't have a good support system that listens and empathizes, find one. You deserve it. You will get well faster if you believe in you. If you believe in you, you will feel that you deserve to get well and you will find ways to make that happen. BELIEVE IN YOU.
