unexplained, uncontrolable sobbing

When I was pregnant with each of my two sons, I would often find myself crying. Generally there was a reason, even if it was only a TV commercial, and when you're pregnant a commercial is reason enough to cry. Very rarely would I cry without a discernable reason, and when this happenned, a few deep, calming, breaths would equal no more tears. Lately I have found myself crying alot, often when I am alone or can be percieved as being alone(the boys are sleeping/upstairs while I am downstairs, or I am in the bath or in my room, by myself.) There does not seem to be any rhyme or reason to this. I can be reading, watching TV, cleaning, folding laundry, trying to sleep, or doing nothing at all. If I am thinking about something sad or upsetting, I can explain it. If I am reading something sad, upsetting, heartwarming, endearing, sweet, whatever... I can deal with it. This is just...I start crying. I realize I am crying. I try to stop. It gets worse. I take deep breaths, with each exhale, I go from crying to sobbing. I realize there is no reason for me to be carrying on like this, and it gets even worse. If someone comes into the room, I can generally stop then, and if not, they chalk it up to me being preggers. If I start crying while someone is in the room, it stops itself before I even really notice. I am rather upset about this, I don't understand really, and I am strongly thinking about talking to my doctor about it. I am afraid that he will tell me it is just hormones, while simultaniously hoping he tells me it's just my hormones. As much as I hate the hormone excuse, it is somewhat valid, and it means that there isn't anything wrong with me. I am afraid, at the same time, that there will be something wrong with me. I have children and a husband to take care of. I need to be strong for them, they need to see that I can handle anything that life throws at me. Otherwise I will be shelterred. No one wants to upset the pregnant woman, no one wants to hurt the feelings of the pregnant woman, no one wants to be the cause of the pregnant woman over extending/over exerting herself. If I am not strong for my family, they will crumble. The boys rely on me to be Mommy. Mommy is damn near to God as far as they are concerned. Hubby works damn hard so that I can stay home with the boys, raising them, and seeing that we have everything that we need. I can talk to him about things that are upsetting me, but he is a "fixer". If something is wrong, he wants to fix it, to make it all better, to be Prince Valliant, the Hero. I don't know what's wrong, I don't know how to fix it, I do not even know if anything needs to be fixed in the first place.

I slept in this morning. I didn't get my hour to myself. I feel out of sorts because of it. Maybe this is contributing. I do not know, but, please, do not let this be a sign of things to come.
