What's the purpose PT.1

Every morning I've been wondering what my purpose is in this life cause right now I feel like I should just end it but I don't  want to make my mom cry but my depression and anxiety just intesifiy's every night and it's to the point to where the demons are not fighting fair and they just keep whispering your not going to amount to anything in this life so just end it and I keep telling them to leave me the fuck alone but they just keep coming back and tormenting me no matter what I try it seems like they never go away and everyday I wish i could go back to when I was young and didn't have this anxiety and these dark thoughts that won't let me eat, sleep or have a smile on my face and i have a aunt that is fighting cancer and I'm praying that she pulls thru so she can make a full recovery and be back at home with the family but it's seems the more I pray the more I start to battle with faith and then I got woke up out of a dream at 9 in the morning on December 24th being told that they are pulling the plug on my aunt and it has me so fucked up that it feels like I can't do anything right but I know that I have to keep pushing to make these songs to make it out of this poor environment and go to where my mind is free from all the stress and depression so it doesn't feel like I'm trapped in hell
