How to restart dancing again??

I used to be really good at dancing and flexible and i really loved dancing since i was a kid. About 4 years ago i stop dancing, moving in general maybe because of my mental health. I got really depressed and lost interest in everything that i used to love. I couldn't even get out of the bed so physical activities were like disasters for me. Now that so many years have passed i really regret leaving dance behind. Even tho i stopped dancing i never stopped loving it and i want to start again but i don't know how. I've tried dancing again but my body no longer move like it used to and my flexibility is also gone. Because i can no longer move like before it's really affecting me a lot. I can't get the motivation to start over from zero again and everything stress me out. Please someone help me.... Please Don't mind my english, it's not my first language and I'm still working on it.
