Positive thoughts please

I feel absolutely low. I caught my sister cheating on her husband so she outted my sexuality to my parents as revenge. Then I find out my cousin died, and to finish the day my boyfriends brother got in my face yelling and pushing me to the point I spat in his face. Ooh and I just know it’s gonna be another great day with picky customers at my job and pressure from my boss. Can anyone give me some sort of positivity? I’m usually an optimist but I just can’t do it right now
