feeling depressed

I feel really sad lately and Idk why. I'm pregnant and I hate this feeling. I suffered with major depression disorder and ptsd and insomnia for a while. But I stopped taking my meds a few years ago. I feel so sad lately but I don't know who to talk to about it. I feel scared for my future and what will come but I keep trying to just let things take their place. Please no judgement. I just feel like I'm struggling.
