Soon to be first time dad

Hi, my partner and I are about to have our first child in 5 weeks. I know I can be a great dad and all, and I'm really excited! But I'm also scared, sooo scared. I'm worried one day she will take our child and we'll end up another split up family in the world, im worried for all the hard times ahead, I'm worried about job security/income etc, it's a total mind fuck and Ive been getting around 3-4hrs sleep on average for the last month and a half, while working 50-60hour weeks. I'm so worn out. Are there any guys out there who got through all this worry and want to chat? I know there's not much reason for all the worry, but I'm living with it none the less while trying to keep it together and be supportive of my partner
