Why are my videos getting no engagement?

I know that it’s part of social media but I came here thinking it was a more inclusive place and a way to become better at using social media but so far I’m not enjoying this platform I spend at least two hours on every post and sometimes even more just for it to get little to no likes favorites or follows I’m not trying to sound bad but I just don’t understand when I see people posting like the same thing and getting likes and comments and shares but when I post I’m not getting anything? #postingconsistently #nofollowers #embracevulnerability #sad
