Irrational fear of balding

[popeye18]

Im not sure if this is normal or if im insane and have anxiety or something. For the past 2 or 3 weeks ive had this obsession with balding. Im always checking my head in the mirror under diffrent lighting. Thing is my hair looks the same as it did years ago. I have a more mature hairline but i have always had that. I dont apear to be balding at all. Everyone just laughs at me when i say something about it. Despite all this i still obsess about it. I remember thinking i was balding when i was 16 for a month or 2 and then i guess i just forgot about it. Am i crazy or is this fear of balding normal. Maybe the obsession isnt about balding at all and has some deeper meaning. Anyone else do this?
