Natural depression relief ?

I’m currently 8 weeks pregnant and yesterday I got hit with such a huge wave of depression and now Im having anxiety with it. It was nothing in particular that got me down , I just physically felt it take over my body. My body suddenly felt heavy, I didn’t want to move or even talk, and I’m spacing out. Then last night while taking a shower I cried for 15 minutes straight. I felt so alone when in reality Im not, I have my other 3 wonderful children. I’ve also been feeling disgusted, I cant say with what. I’m not sure if I’m disgusted with myself or maybe my fiancé? I don’t want to but it feels as if Im losing feelings for him as well. Our personalities clash and we just dont get along like we used to and we don’t see eye to eye when it comes to parenting or financial issues. I’ve tried working on us, and even taking short breaks. Nothing changed.

So any advice on how to naturally relieve depression or at least give myself a break? Ive never had such bad depression while pregnant before and I dont want to take medication while pregnant.
