Hi... Your life has just started and their is enough time to explore everything. Based on what you have shared it seems you are suffering from overthinking, low self esteem, social anxiousness, and uncertainty about something. This kind of constant self judgement may be an outcome of a high moral parenting. This may be an acquired way of thinking you have learnt from an early childhood care giver/role model. Since it is usually learnt and not innate, so it can be changed with little effort and proper guidance.

Do Consult a Psychologist personally either online or Offline.. you can get some clarity and guidance..
