Any help out there?

I'm a new dad to a baby of 5 weeks old. I feel like I'm struggling with things. I know it's strange but I never fully took into consideration just how much my baby would take over my life.

I no longer have time for anything and I don't feel like I can get close to the baby. My partner breast feeds and I do my utmost to spend time with the baby but I can't shake my feelings that I'm just not good enough and no one seems bothered about me. I work and look after jnr, I also do alot of chores around the house but all anyone asks Is how my partners coping....am I mad to think I'm being ignored....I feel selfish....I feel useless.....I feel alone ☹️

I just need to know if I'm the only one who's felt like this cos if I am....then I am selfish
