Dear poster,
I agree with Perna, as she is a wishing well of knowledge and insight!!

A dancers life is filled with passion and is an outlet for releasing emotions.
You have had multiple injuries, very hard to come back from.
My sympathies for your fathers passing.
YOU stated

Yet, I didn´t feel like I could quit, because without it, I felt like I was and had nothing. Also, I knew that deep down inside there was still that old positive passion for dance and I never wanted to give up on dancing.
I never believed that those old and good feelings for it and with it were dead,
just "out of order".

Dancing is very valuable to you, maybe just expand your vision, look at what you can do rather than what you cant. Look at all the knowledge you have gained through training.

The exercises you've been taught, the bar work, balancing, the passion of movement with music is majical.

Think about what you can share and pass down to others.

I dont feel it it is an addiction, it is a large part of who you are.

Things will work out, balance your emotions, and order will return.

Sincerely,
Happiedasiy
