I hate being a single mother when T is sick

I hate being a single mom when T is sick. It is the one time when it feels like I'm "not good enough" because I can't be in two places at one time and I have to come to work and leave this child sick at home. I feel so bad doing it and I feel so guilty because I can't stay with him and because we don't have a full time maid or plenty of money so he has to be alone. The caretaker is there and she will keep an eye on him but man it hurts. he really isn't well so at eight I must phone the doc for an appointment and then I am going to take him and get his medicine etc and bugger whatever anyone here at work has to say. To add to this I am sick too blgggggggggggg
