Need some encouragement

I am a 30M with a 6 yr old daughter. I am a very present loving father.

Few years back I met a girl on dating app. Hung out a couple times then we ghosted eachother. Weeks later she hits me back telling me she found out she was pregnant.

I stepped up and became a father. We never forced a relationship bc we had a kid. We weren’t compatible but played a lot of house for the sake of our child and convenience. Years went by. As a mortgage lender I started struggling to afford rent in expensive CA so in 24 I moved back in with my parents to help save in which I still am here. Last year BM and I decided to both move on. I ended up getting a gf in May and have been in a happy relationship but a shitty coparenting situation. We do our best to do things 50/50. Her mom is a b**** to me but she’s smart and a great mom.

I just found out my gf is pregnant. I’m beyond scared as I am still trying to get my life in order to be self sustaining and be a good father to my 6 yr old and coparent. Trying to work on a broken coparenting situation. Had a goal of moving out by the end of the year.

My gf lives in a room in her parents house. Struggling to make ends meet but is a vet tech at a vet hospital.

This Is her first baby. She’s happy and excited but I am scared as hell and am not ready but coming from an absent father growing up…running from responsibility is not an option for me. I’m scared bc I fear losing my daughter. I fear not being able to provide. I fear maybe my gf isn’t the mom I want my next child to have. I fear we won’t work out and I’d be a single father having 2 BM and being undesirable. I’m not ready and I’m spiraling. I feel like I’ll get kicked out the house and I don’t think we can afford a 3bdroom place between both our income.

Idk what to do or how to act. Any words of encouragement or advice could help. Idk.
