Alone and broken

I’m currently pregnant about 7 weeks along and honestly I’m very depressed like I was in my last pregnancy the only difference is me and my ex are not together at this time and honestly he not emotionally available and I’m beyond sad and regretting getting pregnant again because the lack of support I’m getting at home he’s great with our son but as far as being sensitive or even putting his personal stuff on hold with other females he won’t he swears he wants us to be together I’m feeling like it’s all crap at this point I feel like I have no one to talk to and honestly I already battle with depression so everything is already heightened at this point and I don’t know what to do
