Yes, I have experienced it too. Your self worth and esteem have to come from within. The older I get the less I care about what anyone thinks or feels about me. I care about how I feel about me. Depression and other MI can affect your self esteem. If you are the best person you can be, then be proud of who you are and it won't matter who does or does not see it. One good thing to do is give yourself credit for every little achievement. It will not fix your MI, but it can help in recovery.
