Sometimes I want to be invisible

It seems easier that way, seeing everything around me but no one seeing me. I've been depressed since my aunt died just because she was the one I could run too when I was sad, scared or just wanted to talk. Usually I put on a happy face and just go with it. But on Monday my aunt brought out some toy cars and she told me to guess who gave them to my son. I thought it was my uncle who has a great grandson who is the same age as my son but before I could answer she said Milia which was my aunts name. She said when she found out I was having a boy she started saving cars for him so when he got older she could give them to him. Since then I've been on a downward spiral. Everything annoys me any little thing the kids do anger me. So now I sit up here in my room at my in-laws house crying. I just want my life to get back to normal.....why can't that happen??? Why can't my husband get a job in his career field. AHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!
