It's not too late. You are only 23.

It’s possible in your 20s, if you have the right people and the right environment to thrive rather than survive, and nothing awful happens to shake your world. There is still hope. It never happened for me, and in fact got worse as the decades past but that’s because I had several “shake my world” events to cope with, and I was in an unloving and unkind environment with the wrong person/people most of my life. The kind that tear you down rather than build you up. Don’t be with those people. It will destroy your soul. Good luck!

Depends on the person, some past wounds might take them a lifetime to work-out and heal.

Accomplish difficult things and reflect on your success. Understand what it takes to do those things and recognize that you have what it takes. Aim high so you can learn to aim higher.

This might help you dear young man

Of course

Absolutely it is. It may take work with counseling to overcome its sources, and stepping outside your comfort zone, but it’s definitely doable. 😃
