Hormonal mood swings. A counsellor?

Since more than a month now, I have been planning to visit a psychiatrist but couldn't owing to my schedule. I suffer from periodic depression and mood swings. There are times when trivial things frustrate me a lot. I get irritated, frustrated and angry on people around me. Things such as making noise while eating, not eating in a proper manner or sounds of burps make me angry enough to want to hit the person. In days before my periods it gets worse. I feel depressed and suicidal. I get extremely irritated with everything and everyone around me. I become extremely pessimistic. I have extremely low self esteem and get depressed over little things. Since past two years I have transformed from being a social person to someone who cannot tolerate people around. How am I suppose to deal with this? Should I consult a counsellor?
