You said you want to understand why you feel so bad when nothing is wrong... I thought okay so you are looking for a logical reason why you feel the way you do... But the truth is if you feel bad then something is wrong... even if its only subconscious... and it might not be logical to your way of thinking...

I'm so glad that T and I have not just worked on why I went to therapy. I learned that there is so much more going on in my thinking and feeling that affect my life now that I didn't even know about or let myself deal with...

I had to get to a place of just accepting that I wasn't going to understand how therapy works but I've seen the changes for me...real tangible changes... it does work... but it didn't when I wanted to "understand" it all and to control the session and everything that happened in it... I had to just "trust the process" and then I saw progress... (by the way it felt like the most illogical thing I had ever done)
