What should I do about this mood problem?

The past 4 years, my parents have been going through a terrible divorce. Things are still bad, but I’ve moved out. But they still get to me.

I used to be happy all the time. Now I get mad and upset at a lot of things. Sometimes when my friends joke around with me, I completely snap at them and just start crying.

They tell me it’s because I’ve bottled things up for so long, that I’ve reached a breaking point. I never complained about the arguing and the whole divorce situation. To top it off, my dog of 13 years died 2 days after my birthday.

This isn’t a sob story. I’m not looking for sympathy. I just want to know, if this is normal? Will it pass on it’s own? My friends say I need to talk to a counselor, but they overreact sometimes. And I don’t want to look like that stupid girl that goes to seek help over something pointless.

So what I’m asking is, is this a normal thing that I can make go away? Or should I talk with a professional?
