Sorry you are stressed out bro. To me it looks you have not lost hair. However I would recommend monitoring the situation, as I would recommend to anyone. Take a picture, maybe a few, something you can replicate at a later date ideally. Then in 6 months retake those pictures, replicating the same conditions (length, lighting, style, freshly showered? etc.)
If you notice changes I would see a doctor to discuss treatment options. You could still see a doctor now just for the peace of mind, if you are able to.
Otherwise in the meantime enjoy life! Do all the things you love to do, especially because I'm fairly certain no one would look at you and think there's a problem with your hair.
Best of luck!
