How can I gain gain more confidence?

Find things you enjoy doing. You will be good at them and gain confidence. Spend time with people who are kind to you and say positive things. Try to believe others when they say good things about you. We all have many talents and good qualities. Just notice yours and try to celebrate them.

First step is to answer what area you want confidence in? Is it in specific area or in general? Then to get a specific idea where you don't feel confident enough and what would constitute a success for you. Be as specific as possible but realistic too! Like, if you don't feel pretty enough you can't say that you'd only be confident if you became a super model. Are there any small steps you can take to get closer to your ideal image of yourself? Once you sort out the steps, it can help to have some sort of a chart that would help you monitor the progress. And you have to make yourself celebrate every achievement, even if it feels funny! Once you can see that you are constantly making an effort and there is some improvement, you are most likely to feel more confidence. But then, you may want to make sure first of all that you are not surrounded by people who put you down! Some people just love being critical and you may have internalised their voices!
