The fear of relapsing

Once I was doing drugs every single day for 3 years. I was on the streets living on my own at age 16 and I did drugs every day. I started showing up to school high on X and people started to notice I was so high all the time. 1 day I went on a drinking binge for a week and a half and then I stopped doing drugs for a month or so. All of a sudden my life got better and everything was okay. I got myself a nice girlfriend then we started doing drugs together. All of a sudden I was doing drugs every day again and I didn't even notice. I was so blinded by my love for her and the fun we were having so I never knew what was going on. She got pregnant so we decided to start sobering up so we could get a better life for our child. Now I have a son and things are going amazingly well. I'm scared though because I feel like I'm a 1 mistake away from relapsing. I feel like I'm one drink away from going back to the streets and I fear that it's going to happen. I feel like I'm at a high risk of relapsing and I'm not sure how to stop it. I feel like I'm at a fork in the road and the left side is me doing drugs again but the right side is my beautiful son. I feel like if I make one wrong move I'll be back to doing drugs every day and I'll forget about my son and everything important to me and I really don't want that to happen. I feel like I'm strong enough but I don't know if I am though. I can't let myself relapse and forget about my beautiful son.
