Advice to relieve 🌈 worries

How did all you lovely mommas relieve stress and anxiety during the first trimester with your rainbows!? I had normal everyday anxiety and now after my MMC in June I’m just shocked and need advice on how to control my fears. Baby is measuring 6 weeks 4 days and have heard the heartbeat twice. Even today. But baby was hiding during the ultrasound this morning and gave me the scare of seeing an empty sac 😭 baby was just in the very top corner hiding but took a minute for doc to find. Doc said everything looks good but man. It’s been rough. Especially at night before bed
