How can I practice gratitute, when I get depressed whenever I look in mirror.

[FlightTL]

I keep reading that if you practice enough gratitude, you can change your life, and make it better.

How can I be grateful, as whenever I look in the mirror, I get extremely depressed with my extreme hair loss, looking old, odd shaped head, and huge looking forehead. I get depressed when I look at photos of myself, and see this huge appearing forehead. I feel so bad about it.

I always try and be grateful throughout the day, but hair loss just kills it completely. I end up being depressed, and it feels like my dreams get thrown away due to it.
