Mom to one and can’t support another!

Hi. I am 22 and already a mother to a 1 year old. I live with my husband (baby daddy) and we’re already struggling to make ends meet. We have many problems with just one. My husband is bipolar and currently going through depression, nicotine withdraws and quitting his current job (due to a horrible boss). I am supposed to go back to working full time for a month this Friday but I just got the news a few minutes ago. I took a few pregnancy test and all positive in less than a minute. I’ve been on the pills for months but due to soo much stress in my life, I’ve missed a few pills. Mentally, financially and emotionally, we just can’t support another child. I am less than 6 weeks pregnant (based on my last period) but I live in Arkansas, where abortion is illegal. I don’t know what to do. I just need some advice or a woman that understands.
