Cardiomyopathy? Athletes heart? Or normal heart?

[Matiadbueno94]

Im a 23 year old guy who used to play soccer everyday for a few hours, for about a year until last september. In october i got an echocardiogram which showed that mt LVsd is 1.1 cm and my LVpwd is 1.2. My left ventricular cavity is 4.7 cm. My ejection fraction is 65-70 at rest. And at peak stress it went up to 75-80. I keep freaking out I have  hypertrophic cardiomyopathy. I keep reading that normal ranges for the walls ar up to 1.1 other sites say 1.2. Also how my ejection fraction went up to 75-80. It says 75 is high normal my cardiologist said not to worry, that its cause i did sports. But how can i not worry? Any thoughts? I have really bad anxiety which makes me have symptoms that make me believe i have cardiomyopathy. During the stress echo my ejection fraction went up to 75-80 and my left ventricular cavity decreased, which my doctor said its normal cause the body needs more blood, but it doesnt sound normal. Specially since cardiomyopathy makes ejection fraction go up.
