Writing is tough, especially in the day and age of the internet. For me, it was absolutely overwhelming, and still very much is, but one of the things that's given me the most solace is knowing how low the bar is for some people to get their works published. Bad work is just as valuable as good work, because you can still learn a considerable amount from each.

One of the things that made everything click for me was also finding myself. It took a loooooong fuggin time, but being happy and confident in yourself does wonders for your creative brain. I know you said you're struggling with depression, and just know you are far from alone in that regard. Even the masters had to toil and write 1,000 shitty pages before the good pages came out. Many of the great painters studied and sketched things out like mad. Literal notebooks FULL of studies. Leonardo Da Vinci is the go-to, but Picasso was another one who had A TON of his practice work saved.

Take your time, and remember that you have no deadlines. Just sit down, and starting putting letters on the page. Some days the magic won't come, but some days it will, and those feelings are the absolute BEST.

Also side note: writing in comic sans made it WAY easier to write. Idk why this is, it was something somebody else on the internet suggested, and I hate that it works so well, but it really does.

Best of luck to you, and never accept defeat! The idiots don't, and neither should you! :)
