Worries!!

hello! I'm feeling so nervous for attachment tomorrow! Firstly, I'm really not very sure of how to go to the childcare centre though I have a direct bus there. Secondly, I'm afraid that the new mentor will not be as kind and nice as the previous centre's mentor. Then, as I've been having diarrhea the whole day today, I'm so scared that it would continue tomorrow!:( Not forgetting the fact that we have to spend a total of 10hours in the centre.. I'm so worried that the children would dislike me, disrespect me, ignore me, throw tantrums, cry, etc.... I'm feeling so stressed out right now. HOW?? Will I be late for attachment? will the mentor dislike me? will I make terrible mistakes in the centre? OMG! I'm bursting because of the stress built up in me... Please let everything be okay tomorrow!!
