Oh, yes, I, too, am a believer! I think a lot of times, people with one mental health issue also have others--they go together; the situations that can cause one can cause others. And I understand the irritability that goes with depression--that is one of my signals that I'm more depressed. I get very irritable and snappish. But do take Tara's advice and call for help if you need it. You can get better; I know it. And it will be worth it. Sending you hugs!
