stupid stupid me

im ready to cry right now..am so overwhelmed and scared and worried..my supervisor tells me that she and one of the program directors need to talk to me tomorrow..and she said they had some concerns from the weekend..and i asked what it was about and she just told me that i needed to be there at 11 tomorrow..and i kept asking what i had done and she just kept shaking her head and told me that i would find out tomorrow :( what the hell?! i really for the life of me dont know what has concerned them..and im trying to think back to wait happened over the weekend and yeah i have a few things that could possibly be what its about but i just dont know..and the worry is killing me..i would have rather just have done it all today so that i wouldnt worry..but now they are making me wait..and i could very well go to work tomorrow and end up losing my job and what them ?! i have already gotten one strike against me from months ago..and what ever this is will be strike two..and ill be right back to proving that i can do my job or whatever..but i dont know..i really dont..maybe im not cut out for this type of work..and maybe i just need tof ind something else..and maybe im just thinking the worse right now and i cant help it..im trying to be rational and sane and its not working..im ready to be told t hat im fired..just like that..i mean it all sucks...and its so upsetting and frustrating and im mad...so so so mad because ive screwed up again..and im assuming heavily that my job is on the line again...and some how ill just keep messing up and this will be one more failure to add to the long list i have already ... i just need to go and hide and forget i exist
