Depression and Pregnancy

So the guy that got me pregnant left and no way in hell do I want him back because he mentally abused me and told me to get an abortion and if I didn't that he would leave so I didn't and he left. I know it's been a couple months and I shouldn't care but it still hurts a little and I have to see a therapist because I cry every day I guess a lot of it has to do with hormones.I don't see how someone could be so careless!I'm pretty young so I still have to go to school and he spreads shit about me saying I sleep around and that I did my best friend and that the baby isn't his. It hurts that he would do that.I've only slept with one guy my entire life and I lost my virginity to him and he acts like it was just trash.Anything to do when I have anxiety and depression during pregnancy? No medication because I don't want it to hurt baby.
