You know there are worse addictions

I am happy to hear you love dancing , it deffinitly is worth it and it can give you much in return.
But like with everything else you need to stay in control. If you are worried it is becoming too major a factor in your life then maybe you should take it more slowly.
Take a week off. Just to show yourself you can. And sit down and make a list of your priorities... you know how parents wouldnt let us watch tv unless all the homework was done? Dont allow yourself to dance unless your other life is taken care of
And try to stay in touch more with non dance friends. Otherwise you will be finding it more and more difficult to relate to non dance discussions.
I know I have been through it, though I just traded one addiction for the other and now I am back to the original one: drawing.
P.S.
a forgot, if anyone wants little sketches of teddy bears dancing ballroom let me know, still got a couple lying around.
