Often people will either feel guilty about getting lost in their personal problem because so many others have it worst. Other times, people will try to make you feel better by telling you the story of someone who has it so much worst than you.
Unfortunately, neither situation makes you feel better or alleviates some of the pain (physical or mental) that you are feeling. On the contrary, it probably adds guilt and a sense of failure or/and weakness on top of what you are already going through.
No matter what you go through in life, there will always be someone who has it worst and someone who has it better. Life isn’t a competition. Their story doesn’t invalidate yours. What you are going through is real. Your feelings, your pain are just as valid as anyone else’s.
