First off, I'm so sorry for your loss :( I totally know what's it's like to lose the people you love.
I also have one bad parent- I still have my mum, but my dad is, uh, not present or welcome in my life.
You can always talk to me!! I would love to hear you out!! :))
Listen, life is super rough, and harder on some more than others. Just keep your head high, and you are gonna be such a strong person later on in the future!! KEEP GOING!! :D
Best of luck!!
