Trying to just enjoy it!!

So, this is the 4th time I've been pregnant. My other pregnancies resulted in miscarriages in the 1st trimester. Now I am at a healthy 28 weeks pregnant for the first time EVER!! 😊 The problem is, because of my miscarriages in the past I'm having a really rough time really enjoying this pregnancy and relaxing. Every little thing that happens worries me, and now that I'm a third trimester mom to be, the feeling of helplessness is only getting worse. I feel kicks and movements but not at the level of other mom-to-be's that I've seen or know of. It's just so scary to me to think that I've invested so much of my heart and my finances into bringing this baby into the world and anything could go wrong and I could be heartbroken. Does anyone else feel this sense of helplessness, and how in the world do you stop letting it consume you every day?? Any advice at this point is helpful. 😣
