I think that part of being a parent is going through all the situations that could possibly happen and try to find an answer to them so that if they should happen you are prepared. My husband and I do the same thing, and we were never the worrying type until our first child was born. It even goes to the extent of deciding which room to put our children in just in case someone should break into the house, or a fire, or God knows what else. I think that what you are going through is a natural part of being a mother, and I would speculate that there is probably not a mother out there who hasn't done it to some extent or another. However, it seems as if you are worrying yourself into a frenzy, and speaking as someone with some experiene with this, I can tell you what works for me. I eventually had to find a way to cope with all my fears about something going wrong and this is how I did it: I take a deep breath, hold it in, remind myself that there is no way that God would take me away from my children and leave them to fend for themselves, and say out loud "I'm leaving it in God's hands." and while I exhale I let it go. I make myself feel as if I am pushing out all the fear and worry with the air as it leaves my body. I know it sounds corny, and I will tell you that I am not an extreamly religious person to begin with, but I can say that it feels better to me to know that I can put that fear and worry on someone else so that I don't have to be in control of it. If you have any faith at all you know that it doesn't matter what you do, God has his own plans for everyone. And it doesn't matter which religion you are a part of, if any at all, it just matters that you can let it go and put it on someone else who you feel has more control over it than you do. I know this is sounding kind of preachy, and I don't mean it to, it just works for me, and I think it might work for you. If you really feel like you need to talk to a doctor about it, do it, it can't hurt anything. Hope this helps you out.
