Caught in the middle

I had my first child 6 months ago . I love him like I’ve never loved before . The feeling is just unreal . But with having a child all the baggage sometimes is just too much and overwhelming . Being on my parents insurance still it didn’t cover my pregnancy and didn’t cover my delivery at all . So I keep getting bills in the mail for thousands and thousands . Bill totals that I didn’t even make in the past 2 years . I have no idea how I am supposed to pay them . And to set up a payment plan . Is just pointless I’ll pay it off in 10 years .. I don’t want this to ruin my credit and me never to be able to get a good car or job or house . Literally feel like I’m suffocating because of this and am clueless on how to fix it .
