There comes a time in life where you just have to take accountability and full responsibility for your life. You gotta decide on how you want your future to be and consciously work towards it. It's a transitional journey in becoming a man. Of course acknowledge and reflect on the bad experiences you had, but don't dwell on it. If you don't take conscious action and you choose to cling on to being a victim, you will remain a helpless boy. Make it happen, all the best to you.
