I.cry.all.the.time. My T keeps boxes of kleenex all over her office, there are times I have had the box on my lap. Therapy is hard and it is emotional dealing with things you have not had the skills to deal with in the past. Tears are not a bad thing.
A lot of us probably heard the words "stop crying or I'll give you something to cry about". We suppress the tears because they were never validated.
