Dear Kerry
try not to beat yourself up, being a carer is the hardest job in the world. I had to bring my daughter over from England to help me with her Dad. I was at the breaking point also....my Doctor then prescribed me Zoloft and I used it for 9 months.
Right now even though he is being a bit mean, probably because of the steriods or just stress, he needs you more than the kids.
Can your parents take them off your hands for a while? I honestly do not see how you can be all things to all people right now as your stress level is nearly through the roof....I recognize the signs ...I have been there.

Get some help Kerry...talk to your Doc see if he can prescribe something for you.

Feel free to come on here and whine any time you like ...we are good listeners.

Take care
Marica
