You know when you get advice from a frog of little brain it isn't worth much.

IMO there are times when we need a time out. Those times when pouring a cup of coffee (in your case maybe tea) is too difficult. We snap at everyone in our path whether they deserve it or not.

Let your family know what is happening. They are aware you are having difficulties and will understand. Plus they will know that it is nothing they have done.

When you chill out don't veg out. Do something, anything.
Read a book, play dj and work on music collection, walk, play computer games. Aren't my suggestions original

Don't go into isolation......not good. Talk / communicate with someone. Not family because they're too close but someone.

Of couse my life is such a whopping success that you should follow my sage advice.

I'm very sorry you're life is so grouchy right now. You're a great person. I'm here if you need me.

Take care
