Irritability

So I'm 5 weeks and 3 days pregnant. Very irritable, emotional, sad, and depressed. But to everyone I don't know how to take a joke, or I'm to bitchy, or to sensitive. My SO and I are very happy that I'm pregnant. Sometimes I do feel overwhelmed. I have two kids with my ex and still goin through the divorce process it's been a year. -.- very stressful. Don't really know how to handle it. I've been told it's been a year that I need to get over the hurt and everything from my last relationship. Everyone takes their own time to heal. Also just ready to be divorced so I can focus on my SO, my kids, and current pregnancy. Sorry just venting :(
