You say you're unnoticed and invisible, but for a fact you have 220 followers and 2441 likes. I'm sorry i have to say this on a vent, but what i'm trying to say is that you are really noticed by 220 people and more. And i assure all of them love you not only for your art but also the way you are, the fact that you're an amazing person and a true friend for some people. And it's okay to vent a lot. You always have to let these feelings out when you need too the most. Anyways, i hope you feel better soon. I believe you can be happy everyday if you just try the best you can and even better.
