You got this brother, the right frame of mind is all you need. 25 years ago I was in and out of jail, addicted to crack and cocaine. A total fuck up in life. took a turn at 20, got my shit together, got married, have kids who are aware of my past, I hide nothing from them, they know where I came from and where I have been and the life I had before them. I have not seen a cop in 20 years, have not touched anything harder than weed in the drug department, lost 140+ lbs in last year and a bit, been in same job for 20 years this March. Started on the floor sweeping plastic and now work in the lab, all with a grade 10 education. Basically I am saying bro, you can be at rock bottom and there is ALWAYS a way to the top. And dont worry about your kids looking up to you, you are Dad, they are gonna do that no matter what, my kids do and they know all the shit I did, its what you do with your time with them that counts not what you did before. Even if you do stay a Janitor, there is absolutely nothing wrong with that, there can be money to be made there, starting your own cleaning buisness. Everything is there at your fingertips bro, grab it and run with it!
