Thoughts about myself

Hi, I post content on LinkedIn for my business. I feel like when people like my post, my thought is “Oh I am doing great. This is working.”
And when I don’t get much engagements, my thoughts are
“No body cares about what I do.”
“This will never work out”.
“My post is not good enough.”
“I am not credible enough.”
“People don’t value me because I don’t have a good job title.”
“I am not good and valuable.”
”No one values my work.”

The feeling is Inadequacy, Unworthy

Action: I hide maybe.

What I want coaching on is thoughts about myself. How can I love myself or think positively about myself and not let the number of engagement determine how I feel?
