Feel like I am going insane.

i dont know what's wrong with me but lately I've been feeling really insane. I'm on medications for my bipolar, deppression, anxiety, ect and they work great but I think it is this thing called The Marina Crash that is happening and I don't know what to do. It's hot me super irritable, deppressed, full of anxiety , suicidal, and just feels so unbearable. I feel like I've on the verge of death with a killer chasing after me my nails so desperately scratching on a hard service to get away but I cant. That's the best way to describe it. I've never felt so much despair in my life. On top of all of that today I just sound out I wasn't actually pregnant when I got a light positive and I have been trying so hard for so long to have a baby. I really just wanna call it quits. Time after time it seems like I just keep on failing at getting pregnant.... sorry about the rant but any of you have any ideas what to do?
