I'm sorry to hear that your situation hasn't improved, Lily2.
You've posted more than a couple of times about how unhappy you are in your marriage, and that you feel stuck. Was this brought up when your children were visiting yesterday?
Is that what brought out your anger?
The answer to that Q is key. Something triggered these high emotions that you've been suppressing here & there. Just taking anti-depressants isn't going to help you feel completely better. What really helps is being honest and sharing these thoughts and emotions with a professional ~ someone who can help you put things into better perspective. Then, you can work on how to make your life better.
I agree with dark heart, about apologizing for your behavior. That can help you feel a little better too, because you're accepting blame for the blow-out & that lets go of the guilt inside.
Best wishes to you!
