You will never rise out of the fire if you can't face your demons, brother.
Identify those motherfvckers and face them head on. That's the only way. You have to stop hiding. Posting here is a way of hiding, as you mentioned yourself, because no one knows who you truly are. It's like you can secretly admit your faults but no accountability is behind it. Share these things with your mom, dad, sister, friends, whoever. They will support you if they see you putting in the effort to change.
Own your shortcomings. Decide to overcome them. I suggest listening to a few David Goggins videos... that man overcame all kinds of sh!t. From being 320 lbs man abused as a child and spraying for ****roaches for work to a Navy Seal, Ultra runner, among many other things.
Go to therapy.
Strong men handle their sh!t, and you're going through some sh!t right now. We all are. Nobody that matters will judge you for trying to be better. Only insecure people judge people. I cannot speak for everyone here, but I would respect you more for going to therapy and handling yours than I would for you being scared of taking the steps to change. I know it's tough. But if you believe the benefits outweigh the struggle, you'll go through it. On the other side of struggle is greatness.
Tell me this; Do you respect yourself? Are you proud of the way you handle things daily? If you are, then stay the way you are and fvck what everyone else thinks. This is your life. If you aren't, then do something about it and fvck what everyone else thinks. This is your life. How can anyone respect someone who doesn't love themselves? A DJ puts himself first, start putting yourself first.
Look in the mirror, tell yourself the things you dislike about yourself. But only if you're willing to change them. One thing that we can all take away from your journal is that it requires action to become anything other than what you are. "Insanity is doing the same thing over and over again and expecting different results". Go get yours.
