I've been there and it sucks. Again, my best advice is to stay steady, no big decisions, no big life changes. Trust your gut. You will be able to work through it all in time and be stronger on the other side. It sounds like you have some supportive people around you, so lean on each other. Let yourself feel your emotions as much as possible so they don't bottle up and make you mentally/physically sick. Practice mindfulness and focus on things you love. Distract yourself with nature or a silly movie. Lean into your faith if you're religious. Good luck and I hope it gets better soon.
