Constant crying was the reason I first sought help with my depression. I cry easily anyway, but this was a daily occurrence I've found I do much better with a female therapist, but that's just me. I also found out though my family doctor that I had a severe electrolyte imbalance. My potassium was 2.0. an extremely low reading that could have been life threatening. I have constant diarrhea (tmi?) which caused the problem. but once it was under control and my potassium returned to normal, the crying stopped. Perhaps you need a medical checkup as well. I wish you the best of luck in resolving this.
