Hi, Mike. Here's something you may not be conscious of, but look at your first paragraph. You wrote, "I felt relief after talking to her but I dont know how long that will last." As many people say, everything before the 'but' is negated by the second part of that thought. In other words, "I don't know how long that will last" leads into negative thoughts.
Someone was telling me on the weekend that he was so bullied when he was young that he knows he accepted some of the messages given to him at that time, such as being stupid and no good and unable to do anything right. Actually, he's none of those, but he says he that over time, he's played those messages to himself in his mind so many times that it's automatic. I hope your therapist can help you those kind of things, things that should be challenged and questioned now. All the best :)
