I've been a single parent now for around 8 years and it's great. Sure, you have to be the strict one from time to time but you get all of the benefits of watching them grow up.

The only advice I can give you is to take some time for yourself. You are not a super-hero and you will need to have time to wind down with friends. That's not easy if you are working (I know this, I work 120%) but you need to be able to have fun too. And you should not feel guilty in any way.

There will be challenges and there will be hard times, but you will be a stronger person for it. Have fun when you can and your kid will love you anyway because you will be more relaxed as result.

Good luck.
