I think the hardest part isn't letting go but accepting that something you wanted so badly is not meant to stay.
Atleas I though that 2 years ago about art, life just turned upside down and I couldn't manage real life with art anymore. Tried everything to keep art with me, but at the end it wasn't working out. At some point I got tired of trying and finally realised that letting go wasn't losing but giving myself a chance to breath and figure things out.
And it was true, finally after 2 years I managed how to deal with work and finally be abble to relax, make art and still being active on social media.

Alot of things would be different if I didn't leave but I'm pretty sure I wouldn't be this happy.

Don't be afraid to let go, sometimes is all you need and you don't even noticed.
