I have had similar crying spells - over the past few months. I will be driving down the road and have to pull over until it stops. I will be litening to a radio program, and hear something that would not necessarily make me cry, but there they come.
I talk to my best friend on the phone, and he will say something nice and supportive to me, or I will be telling how much his friendship means, and off I go - he's been really wonderful (he's also a survivor- so he understands) and I just sob for a bit.
I was freaked out at first... and I still am uncomfortable by the loss of control, but I think it is a sign of healing, of letting those feelings come to the surface - that's how it feels for me.
Mic Hunter, in his book Abused Boys, talks about sadness being a stage of recovery - and I have been sad - about the losses I've had and the patterns I've developed... but maybe we are moving forward.
Don't know if that's how it feels to you.... hope this helps
