Really cool to read all your own story!
I started being interested in yoga back in 2013. I had back and legs pain and it came to a point where it kept me from doing some everyday stuffs, so I started doing it with videos. But then, I was so not flexible and not in the mood than I quickly get discouraged.
Still I kept doing meditation and as a girl who struggled with depression and anxiety (bcoz of learning disability and attentional disorder) all her childhood and teenage years it really, really helped me.
A bit earlier this year, I had suddenly a lot of free time so I decided to return to yoga practice, but like @IzzyDramaLover I had a bad experience with a teacher (+dirty room) so I just quit and looked for a yoga class online. A few weeks ago, I found "yoga with adrienne" channel and since I did about 20/30? of her videos. She has tone, suitable for all levels and a lot of beginners videos. The teacher is really kind, friendly and patient in her tone makes me feel safe and comfortable following her videos. . Plus she's not pushing anything, is very easy-paced in her beg. videos so that you can slowly learn and take your own rhythm.

What my yoga and meditation brought me? The ability to stay focus, and I agree with @Tania and @samsoons, one of the pros of yoga it's definitely its capacity to teach us how to stand and walk in good posture.
