I am depressed

I stop taking my antidepressants as soon as I found out I am pregnant. Now my depression is back worst than it’s been before, see I stayed with my cheating husband because I have other kid, I don’t want to be a single mom plus I am afraid of divorce possibly losing my house, starting all over. This weekend the depression as hit me like a ton of bricks, currently at 27 weeks. I wonder if I can start taking my antidepressants again, I have an appointment on Wednesday with my doctor but till then my whole body hurt. I need help
