No: Lukas, you're a grown man now and you recognize that you have health concerns that are unrealistic. In a way it's good -- you'll be more vigilant -- but if these fears are preventing you from finding the peace you need to work, play and love, then some structured self-exploration might set you free. Be brave, and best wishes.
