I’m sorry you’re feeling a lack of confidence; I’m sure you have many wonderful qualities, and a lack of confidence often means we accentuate our faults and overlook our virtues. It’s important to know that many people suffer from the same problem: it’s called “negativity bias,” and seems to be universal. But sometimes it governs too much of our lives. If you find it’s getting in the way of living a full life, I recommend counseling (bit.ly/BC-counseling). Also, just look for ways to turn down the volume of the negative self-talk, and turn up the volume of the talk about your virtues and past successes.
