Sometimes the hardest thing we can do is put ourselves first, when it feels like we are letting others down. But you cannot live your life for other people... I have lost count of the number of times I have done stuff I didn't really want to, because I had promised that I would, or I knew it meant a lot to someone else, and more often than not I felt resentful and regretted doing it and was annoyed afterwards that I had let myself be persuaded into it. Especially when it comes to something like performing - you have to want to do it for YOU and know that you will enjoy it etc even if it is scary - I think deep inside you can tell the difference between pre-performance nerves and OM MY GOD I REALLY CAN'T DO THIS ESCAPE ESCAPE especially as you have performed before, so it's not like you just have to get over the initial cold feet. At the end of the day you would know if you really wanted to do it, and you would find the motivation to push through your problems if that was the case. Listen to your gut! I would definitely say I am much happier in myself now that I know how to say 'No' a bit more, and not feel guilty about it!! ;) I often joke 'well I USED to be a nice person haaaha now I do things for my own sake', but if you try live your life any other way it only ends up in misery for you - and at the end of the day YOU are the only person you have to make happy. Fuck everyone else quite frankly ! =) and if the studio owner wants to be a dick about it I think that says a lot more about her than it does about you - I only know you from on here but you seem like such a lovely person, and really kind & considerate, so even I can tell that you would not make this decision lightly - if she cannot see that for you to drop out at this stage was A) a real internal battle for you B) obviously due to real tangible reasons which you could not overcome then she definitely does not deserve you bending over backwards to please her at the sake of your own wellbeing. It sounds like you have a lot going on right now and I find whenever life is pressing me down it affects EVERYTHING, you can't just switch off feelings when you are trying to deal with shit haaaha ohhh noooo it wont let you until you have resolved it within yourself. The fact that you spent the weekend in bed sounds like you are fighting it from all angles, and your brain is struggling to cope with it all, so the looming performances are just another stress ball adding to your head-fuckery rather than something fun to look forward to, which it might well be if you were in a happier head place at the moment. That's the thing with a performance/competition entry - it is stressful!!! So it seems different to when we are just dancing for the fun of it - because you are trying so hard to do your best, and are always so critical of yourself . I remember feeling like that last year practicing my routine for a competition video entry, it was all very rushed to get it submitted in time and i was so mad at myself everytime i messed a bit up, because it felt SO important. I remember thinking that exact same thing 'goddammit i thought this was supposed to be FUN what the hell why am i so pissed off then AARRGGHHGHG ......' But I could still feel that I really wanted to do it, and it was easy for me to get up and run through the routine again & again... so yeah I would say listen to your instinct, how do you feel now that you know you won't be doing it? do you feel relieved, or do you feel a pang of regret you are missing out on the experience? If the only reason you feel bad is because of letting the studio owner down then you are doing the right thing.
Sorry for the essay haaaha but this really resonated with me, I really feel for you and want you to know that it is OK, even essential, to be selfish sometimes. Because at the end of the day YOU are the only person who will ever put you first, so we have to look after ourselves first and foremost before we think about doing that for other people =D
