@Klaustasya I want you to know that despite what you think or feel, you are NOT alone!
A bit about me. I'm married, no kids, surrounded by people I can talk to, BUT (here is the kicker) I have diastatic depression meaning while I don't suffer from big bought of deep depression, I will never be happy. I live with a constant cloud of contentness or meh about everything. I know this lonely feeling cause it's my every day reality, but what I can tell you to help is connect with others on things you enjoy. Art? Connect with other writers, do some collaborations that force you to be active. Surround yourself that push you to be better. Create a circle of improving each other, maybe even have weekly voice/video meetings.
Try new things like meetup.com to try things that have peeked your interest. I have done it for years and ALWAYS found 99% of people are very welcoming even for completely clueless people.
If you need to talk we are here, but feel free to reach out via IG "DarkDekuLord", cause I'm bad at following up on forums, but if anyone just needs to vent or whatever please don't feel like you have noone. I might not be able to solve your problem, but I can at least be there.
