Don’t feel guilty. Everyone has their own struggles. You can look at people who are in worse situation to get some perspectives in live. If it helps you to be positive that’s ok. But don’t use that as a way to disregard what you are feeling and why it’s a problem and how you may solve it. I call it “don’t be grateful someone stabbed you in the leg just because someone besides you got stabbed in heart and died”. Yes you’re better off, but you still need to worry about you and get better.
