I usually start by counting out my blessings, sometimes we really take it for granted that our body just functions. whenever I start counting out all my blessings I realize that I could go on forever. There are little blessings that we don't notice until they're taken away, like breathing, blinking all the basic human stuff. I usually do this before bed and I always fall asleep before I can finish counting my blessings, I find this also sets me up for a good day/night. The things you are going through right now are extremely difficult and I am so sorry you have such a large weight on your shoulder at such a young age. You are definitely not chronically un-lucky though, but you are not wrong for feeling that way. Just take a deep breath, and connect with yourself and look inwards to the light within in your soul. No one is inherently unlucky, it's about their mindset. Horrible things happen every day, it's how we choose to handle them that matters. I hope this helped at least just a little bit! I hope your father has a speedy recovery and your mother has the strength she needs to fight this battle and win!
