1. Don't say 'You don't look sick'
It is important to not make assumptions about someone's health based on how they look. A person with a chronic illness may not always look unwell due to medications they are taking or other treatments they are undergoing. By telling someone they don't look sick, it can invalidate their feelings of pain or fatigue and make them feel as though their condition is not being taken seriously.
2. Don't say 'Just take a pill'
Many chronic illnesses do not have a cure and cannot be treated with just a pill. A person with a chronic illness may need to take medications, but it is not as simple as just taking a pill. It is important to understand that a person with a chronic illness may have a complex treatment plan that includes many different medications, therapies, lifestyle adjustments, and more.
3. Don't say 'It could be worse'
This phrase is often used as an attempt to make someone feel better, but it can actually have the opposite effect. It may make the person feel as though their feelings are not being taken seriously and may make them feel like they are not allowed to feel sad or frustrated by their illness.
4. Don't say 'I know how you feel'
No two people experience a chronic illness the same way, so it is not possible to truly know exactly what someone else is feeling. Even if someone else has the same condition, they may have different symptoms or a different level of pain. It is better to just listen to the person and validate their feelings without trying to compare them to your own experiences.
