2ww how to not stress out??

Just starting my 2ww (month 10 TTC). We started trying some new things last month, so this is the first full cycle with all those extras (new vitamins, preseed etc) coming into my fertile window I was feeling super hopeful, but now I'm feeling really anxious and emotional. I can usually hold it together pretty well until the last few days of my 2ww but I'm already feeling like a total mess. I know stressing myself out won't help anything and I don't want to set myself up for major disappointment. Anyone else due for af  around the 30th? Could really use some support and prayers!
