I used to be self conscious. I had low self esteem, poor body image, anxiety and depression. I know from experience that these things can be overcome.
This is a difficult situation, because while self awareness is a powerful transformer, that focusing inward can potentially lead us to become more self conscious. When I feel self conscious, which still happens, but not nearly as often or intense as before, I accept that those feelings have arisen and allow them to be there. I don't focus on them however. I simply notice them, and that's all the attention I give them.
Self awareness can help heal our inner dimensions. When we allow those awkward and painful feelings to arise and accept them for what they are, painful feelings, then we come to know ourselves better at a deeper level, and those painful feelings can transform. Treat yourself with unconditional love and kindness, it will help promote healing both physically and emotionally. You deserve it and so does your body.
Also, being self conscious means that you are probably highly sensitive, making you potentially very empathetic. This, combined with being visually afflicted, as with acne for example, can potentially allow you to create even more depth and therefore keenly attuned to the pain and suffering of others. Having this depth of awareness can be quite satisfying when we allow ourselves to love who we are and then share that love with others.
The joy of being is the joy of life, loving what is, as it is.
