I might have a messiah complex.
What makes you think you have a messiah complex?
Its because everything in my life is perfect.
You should feel grateful for the life that you have been given, without believing that you are an extraordinary being because of it. Use your good fortune to help others because no one will remember you for how good your life is.
Everything you said makes sense, but it doesn't stop me from having a messiah complex
Then use those feelings as fuel to help others less fortunate.
