Should I see someone?

So yesterday I completely broke down and I'm not really sure why.

I hadn't cried for nearly 3 years. It really freaked me out. I don't like to lose control and that is exactly what happened I lost all control and I don't like it.

I'm an interverted person for the most part, not that I don't like being with people I just prefer to keep to myself.

My boyfriend hasn't noticed a change in me today but my thought process is all out of wack right now.
Mom not surprised he doesn't noticed, I am reserved by nature.

I do not think I am depressed but I don't feel the same and I'm not sure why but this is starting to eat away at me.
