Pregnant from rape

2 weeks ago I got raped and found out today that I'm pregnantand I'm devostated.
Has anyone been in a similar situation and kept the baby? 
I'm 18 and have been recently diagnosed with bipolar aswel. 
Everything is just spiralling out of control and I'm not sure what to do. 
I'm on meds for the bipolar and I need to talk to my psychiatrist about if I can take them while pregnant but I don't even know how to bring this up. 
Anyone got any advice?
