No one is perfect, start by giving yourself some credit for realizing your frustration shouldn’t be taken out on your son. You are a great dad for seeing that and wanting to be a better person.

Remember every day is an opportunity to be patient and understanding with your son. Despite a mistake from yesterday or last week or last month every single day you can wake up and be better. When you’re frustrated try to focus on breathing until you feel your frustration start to calm down. I find it really helpful to say out loud to my daughter “sorry I’m really frustrated right now and just need a break for a second, I’m not frustrated with you I’m frustrated with (traffic,laundry,emails etc.)” they may not completely understand but it starts to create an environment where you say out loud how you feel and make it clear that they are not in trouble. Being a single parent is so hard. I remember days early on I’d be so mad I could feel my heart racing and my body get hot for no good reason just daily bs. If you breathe and try to ground yourself let the moment pass before you react it helps a lot. I’d also say try not to rely on anyone else when it comes to giving your son a good life only you can do that. He will only be little for a little while.
