Hard choices

This is my first pregnancy it was unexpected and it is unwanted on my end. My partner wants to keep it and is pressuring me to. He is unstable and irresponsible. He is a recovering addict and is unemployed- has been for a year. I feel like I have no choices that I can live with. I don’t want to terminate. I don’t want to bear that guilt and shame and I don’t want to lose him. I don’t want to parent and bring a child into this toxic situation and be the sole person responsible for raising the child. I am depressed and full of anxiety and have been having panic attacks almost daily. I feel hopeless and and powerless and terrified. I don’t know what to do.
