I suggest joining game jams here on itch. They tend to help with productivity and motivation which I know a lot of us struggle with.
Also if you join a rated jam then you get to vote on other participant's game and they can give you a rating and feedback on your own.
What I have learned and I don't mean to sound condescending in any way when I say this; we are small fish in a HUGE pond and a lot of us want to think our games are special (which they are, they are something to be proud of and treasure forever) but we must have a bit of give and take. Try reaching out, giving someone else's indie game a whirl and giving some constructive feedback on their game page. Hopefully, they will appreciate that and try yours out too, but there's no guarantee of course.
But anyway don't give up if it's what you love. All the best :)
