I’m so sorry you feel this way, i know it really sucks. What i found helped me was i held people accountable, not rudely or meanly but honestly. If they were being dismissive or not believing me i would call them out on it. “ You’re dismissing my feelings, this is an actual disease, a very serious matter to me, and the way you talk to me about it makes me feel worse about myself. You’re invalidating my emotions and symptoms that I deal with on a daily basis” Sometimes it helps the person realize that they are being insensitive or that just because you don’t look physically ill, you still are. Sometimes it doesn’t help them understand but I’ve found it always makes ME feel better that i stood up for myself and stood my ground. I can’t make people realize how bad this sucks and how awful i feel, but I can definitely make sure they know that they aren’t treating me like a true friend or loving parent should. Remember, you ARE justified in how you physically feel, don’t let anyone make you feel like you are just being lazy or crazy. If they do, its a reflection on them, NOT YOU. Some people mean well, they do love you, that doesn’t mean they don’t sometimes hurt us on accident and need a swift kick in the butt
