help please I just need some guidance

I’m going through hard times. I’m 19wks pregnant with my son.. I have a 2yr old. Same guy. I am just so depressed… I don’t want to continue this pregnancy, thinking about adoption. He is making my life so hard right now I cannot believe I’m in this predicament… I need someone to talk to before i lose my mind and i have nobody…. Even if you just listen…
