Am I worrying for nothing

So I'm still fighting with insurance and I'm 12w 6days. This is my second child and I developed Anxiety and depression right after first. I keep getting this terrible feeling about this pregnancy, it keeps me up all night. Bloating is gone so stomach got smaller. Nausea gone and no longer tired. Boobs still hurt, but that's it. I'm terrified once I do see a doctor they aren't gonna find a heartbeat. Trying to relax and remain calm, but once it gets in my head I start shaking and freaking out. Talk me down someone. Please!
