Separation Anxiety

So I have been back to work for almost a month now and the separation anxiety that I had from the first time I left him is still holding strong. I'm lucky that our little guy is currently being watched by my aunt and then my mom for the entire summer since she is a teacher, but the mere thought of him being in a daycare come August literally makes me sick to my stomach. I'm just terrified that something will happen to him because the daycare worker doesn't just take care of our son, but many others as well. All of these "what if" scenarios just keep popping into my head and I can't make them go away. On top of this, I just found out I'll have to travel for work in February (yes, 9 months away from now) and I am already a nervous wreck about it. I actually had to go into the bathroom after talking to my boss about it and I broke down in tears thinking how I won't see our son for 5 days (typing it out right now is making it even harder to imagine!). I really thought it would get so much better; at least that's what everyone told me, but it just has not. I guess there are a couple feelings at play here. First is that I know how easily people (especially children) can be ripped out of your life and I want to spend every waking moment with him so I don't miss anything. Second, and I think the one that bugs me the most, is just the complete distrust I have for professionals whose job it is to take care of babies and kids. Logically I know that this all stems from how awful our OB was while pregnant with Ava, but it just keeps spilling over into ALL people in this field. I don't talk about it often, because it's so painful, but the OB we had while pregnant with Ava was partly responsible for her passing. If she would have been attentive to so many things she wasn't, we could have caught the Parvovirus earlier and possibly treated Ava while in the womb (and have her here with us now). It's this exact reason why I am terrified of someone else taking care of him. This anxiety has gotten so bad that I even discussed with my husband the possibility of me quitting and being a stay-at-home mom. While that would be the most amazing job in the world, I know that right now it isn't necessarily the best financial move. Although it wouldn't work for now, we did discuss how it would be a feasible option if we ever have another baby. Is it terrible that I thought about getting pregnant as soon as possible just so I could stay home with him and the new baby? I know that it wouldn't be the best (for my health or the baby's) but I just want so badly to be home with our son. I guess all I can do is take it day-by-day and hope that this anxiety starts to lift as time passes.
