Discouraged

When it comes to being creative, I continue to be more active on Twitter than anywhere else, & my account is here: https://twitter.com/TheBaldVegan
My last book continues to be an absolute failure.  No one has bought it.  I'm considering changing the title.  Obviously, I have nothing to lose.  It is here on Amazon: https://www.amazon.com/Farts-Literature-featuring-Bald-D-Bag-ebook/dp/B074MCFPVD/ref=sr_1_2?s=digita I haven't been working on my next book.  Considering the lack of interest in this one, it seems like a waste of time.
I've been taking Lexapro (an antidepressant) for almost a month now.  I still think that life sucks.  I still wish I'd never been born.  I still think it's selfish and cruel to bring people or animals into this world to suffer, as all sentient beings do.  So it's not working any miracles.  It makes me more wired, more irritable.  It has definitely affected my sleep negatively.  I tend to get up very early, no matter what time I went to bed, and then I can't get back to sleep.
Antidepressants won't cure everything.  As long as lots of animals are suffering to the degree that they are, I will be depressed by it.  Antidepressants won't get me out of my dead-end "career."  I am an "unskilled' worker.  The thought of going back to school to improve my work situation is a daunting one.  We're guaranteed nothing in this dog-eat-dog world.  I could spend a lot of money and time training for a certain job, and then not get hired for it.  I still have to shit, piss, and blow my nose frequently, all of which I hate.  And there's all the other boring, annoying, soul-destroying things that need to be done everyday: like brushing teeth.  I still hate to drive; it's so stressful.  I have to share the road with tons of stupid, careless people, who could ruin my life (even worse than it already is) in a heartbeat by causing me to get into an accident.
So I'm still very much discouraged when it comes to life.  I have very little hope.  I had great hopes for my book that no one has bought.  I still believe in it; I think it's funny.  But, as I've mentioned before, I'm just one of billions of human ants, desperately trying to be heard, and, as always, failing.
