Well. 1. You severely undervalue yourself. 2. You are abused at work: overworked and underpaid. 3. Rock-star programmers and ninjas are bullshit "titles" meant to shine some lights on successful introverts to attract some other introverts into abusive companies. My best advice, if any, would be to find yourself a hobby or any activity with which you can gain back your confidence: sports, crafts, cooking, etc. Then, work on showing value rather than chasing recognition. Your work and skills are most certainly good, but since you're devaluing yourself, you're probably devaluing them as well. And people (peers, bosses) actually do use it against you (willingly or not), fueling the vicious circle. Last, learn how to do I interviews and start fresh on a new job. I personally have learnt as much interviewing with 30+ companies than trying to uncover my own worth. Why? Because you can change some parameters at every new company you meet and discover for yourself how your discourse is perceived and how much real people think you're worth. I've applied to jobs 2-3 levels above where I was just to rebalance my then actual experience with the "market" and I've learned a ton! Most companies you will never work with/for, so you might as well use them as tests for when you will get an interview with a company you really like. But first: get some confidence back.
