Abortion or adoption ?

I’m 19, have very bad mental health issues, and psychical health, I don’t know who the father is, I use condoms, and I will be going on the rod when I can, I’m freaking out I’m getting an ultrasound tomorrow so find out how far along I am. I really need some advice or kind words as my mum wasn’t so kind to the news. Please help I’m so scared, I’m from Victoria Australia.
