I am taking too long

I was talking to Grace today, and she asked me to do something with her monday, but I told her I couldn't because I had a meeting with Lila, and she was like "still, she hasn't fixed your problem yet?" I just sat there, I didn't knwo what to say. I mean I am I really taking too long? How long do people usually go to a therapist? I guess it just made me really think...should I have already "gotten over it?" She just made it seem like it was a "problem" and I guess it is...but it's not my...I don't know. she just made me feel like a complete Idiot! I don't know what to think. I always think I am wasting Lila's time because it's like I never can talk about anything that I need to. I DONT KNOW! mybe I should just stop wasting her time and stop going. I am evidentally not going to ever get any better. this is frusterating.
