Stressed and pregnant

So, I’m about 16-17 weeks pregnant and this is my third baby but my youngest is eight , so it’s been a while.  I feel like I’ve had a cold or flu or some thing lately because I’ve had a bizarre symptom of under my chin (in the middle, not on the sides, being really sore and feeling swollen).

I’ve also had worsening symptoms over the last couple days of stomach pain/cramping and back pain . I have no support system where I live and really struggling right now my partner lives in another country and this is his first baby. He often tells me I’m acting “like a child “ or that I’m acting mentally ill, when  in reality, I’m just pregnant AF. 🤷‍♀️ 🤰. I love him and really hope soon he will be here with me because im getting  extremely disheartened and stressed and worried about continuing doing everything while being pregnant and all by myself. Plus I know if he was physically here our communication would be better because he would see the actual struggles and changes a woman goes thru when pregnant. 

I’m really struggling right now, and could use any uplifting words of advice or comments, just because my midwife told me to monitor the cramping and that stress can really do a number on us pregnant women and it’s been a while and I’m just scared, which isn’t helping.

Does anyone have any advice on things to do to help me relax or to help cramps or pain or anything like that? I would be so grateful.
