//The biggest inspiration, lately, has been reading books! I've found a book series, which was rec'd to me by a friend that has a character similar to how I portray my Andrealphus. By reading this book, his muse, which was on death's doorstep, came back to me!
This ties into my second inspiration: constantly going back to canon media for my muses. Every re watch/re read/replay ends up bringing something new and fresh to my mind, and I end up applying it to my portrayals, or it fills me with a desire to write!
Music is yet another source of inspiration for me. Having a good playlist going in the background while I write puts me in the mood to write!
Lastly: Taking breaks and getting plenty of sleep. I find that I am able to write when I have a proper sleep and break from work irl. Sleep does so much wonders for your brain chemistry and mood and I can't recommend it enough. Stepping away from writing for a bit to either read or do another hobby also helps, along with not being on the dash 24/7. Being constantly on your rp blog is a good way to burn yourself out and aggravate your anxiety and stress, so taking frequent breaks is good!
tl;dr: Engage in other hobbies and take care of yourself by eating, hydrating, sleeping, and taking breaks from your dash are excellent ways to gain inspiration for writing! Never try and brute force your way through burnout, anxiety or stress; it won't end well for you and your writing will suffer because of it.
