Sharing Our Innermost Thoughts

Hello, I am a college going middle class girl. I thrived for a better person in myself, making me believe that by asking various people of the weird or bad things they observe in me, with which by improving I’ll be able to help myself. At first it went fine, when people said what they felt and I introspected it in myself, making me carry forward with the changes I felt relevant enough and ignore the rest. Until I started getting confused and lost, between who I am in reality and what I presumed myself to be, between what is relevant enough to adapt and what to ignore, between whether the points mentioned by someone are concerned with me or are they reflection of their insecurities.
Being an extreme extrovert and highly expressive I had huge group of friends and many close ones too, but today I have lost it all in this fight within myself. I have no long term bonds anymore, I barely have people around me anymore. And this is really tough for me, from being a people’s person to to be all by myself.
Today I am just occupied with these tug of war instead of focusing on my crucial period of making my career. I need your help.
