Hi
Start with becoming non judgemental first about yourself and others too. Stop overthinking and opinionated . I see that you may be falling into the trap of feeling inferior about self
Next Steps
With correct therapy and counselling, you should just be fine, don’t worry . Yours is not an illness or disorder, it’s just yours thoughts that’s resulted in more thoughts and then only negative thoughts that has remained now . This is on basis of what you have shared so far
