ever want to run away?

I had my son at 18 and ever since then all I have wanted to do was pack everything up and take off to somewhere and have a clean slate and adventure. Every time I got more serious about leaving something would always hold me back, my parents, myself, thinking about going to school, but most of all my sons dad who hasn't been around at all (even though our relationship lasted 4.5 years 🙄). It has been a whole year since his dad has seen him and he's been mute since and I've been dating someone new who is the COMPLETE opposite of my ex. He is so wonderful, caring, and supportive. But I can't help but always have this pull to leave this town, its suffocating me here. Working day shift everyday and loosing all this time with my son I feel like a robot and I feel like I'm missing out on life but at the same time feel like it would be completely irresponsible and selfish to do that with my son. I don't want to let anyone down or make a huge mistake and my depression could swallow me whole most days, I don't know if I'm trying to run away from my problems or what but all I know is that I can't breathe.
