Pregnancy depression

I have borderline personality disorder but lately I’ve just been so depressed since 34 weeks hit (35 now). I don’t wanna get out of bed, I feel like a pain in the ass and like everyone hates me, anxious to the point I think I hear people pulling into my driveway when nobody is...... i don’t know why this is happening. I deliver in 8 days (isn’t safe to go past 37 weeks) and I’m so scared I’m gonna have postpartum.
