22 weeks pregnant with a babygirl at 16 and freaking out

I’m currently 16 and pregnant, I loss my last job a couple months ago due to personal reasons, I live in Colorado Springs and I’ve been freaking out. I been applying for jobs the second I got fired and it seems as if nobody wants to hire me, I’ve been working since I was 15 and have experience, I’m showing even in xxL clothes, before I was pregnant I was extremely underweight due to an ED I was (99.1) and now I’m 126.0 and it’s been causing me to feel extremely bad about myself but I know I need to keep gaining weight and eating for my daughter. My fiancé has been with me for 4 years and has been doing everything he can to make me feel better, he even started a 2nd job so I “don’t have to worry” but it makes me feel so bad He’s been helping me with my mental health and stress and I’ve lost 2 close family members this pregnancy and having to go to funerals, I just don’t know what to do, I’m still applying for jobs but nobody wants to hire me I had a manager even tell me “good luck finding a job while being knocked up at 16 nobody wants a pregnant employee or a irresponsible person”
