Va medical

I’ve been seeing my va therapist for a little over 2 years. She’s a really nice lady but I don’t think she understands me. She downplays everything I’ve told her. For example, I mentioned to her that I cope with my symptoms by over eating and my struggle with weight ( 6 feet 280pounds). She replied “You don’t look that heavy.” Another reason that I’m not too fond of her is because she just wants to push meds on me. What’s a good way to part ways with her without offending her?
