Why was I denied mental health services by the VA due to my having a power wheelchair for my service-connected disability?

SN Debbie Blackburn Ma'am we need more info to help. From your brief statement, it is not clear what actually happened or was said., From this end, "Why was I denied mental health services by the VA due to my having a power wheelchair for my service-connected disability?"
makes as much sense as "Why was I denied mental health services by the VA due to my having a banana for breakfast last week?"
How did the VA phrase the denial of services? What does the wheelchair have to do with it? What is the connection between the wheelchair and your request for services the VA office is making?

Confused here. What specifically does your being in a power chair have to do with being denied mental health services? Until such time as more specifics are shared, there is no way anyone can properly answer this.

We need a lot more information to provide helpful responses. My wife uses a powerchair to get around. We have not had an access problem at civilian or military medical facilities. Your RP profile needs to be completed for us to help. For example it makes a big difference if you retired or not. Also are you covered by Medicare or Medicaid? Help us help you.
