Im scared and excited

I just found out I’m pregnant! I’m so scared I’m only 20 and living at my bf parents house. I feel like I’m a failure because I’m not in a good spot to be pregnant. How do people do this?? The only person supporting me is my bf and it’s hard cause sometimes I need a mother figure or someone who has had kids and can reassure me. Omg I’m so overwhelmed. I have so many thought going threw my head already and The more I talk about it the more I start to throw myself into a panic attack. Don’t get me wrong though, because I do want this baby. Any advice idk just anything at all would help. I’ve never baby sat really and I’m scared I’ll be a terrible mother and I’m just going to fail before it’s even started.
