I think that for most people, that kind of work is soul destroying over a prolonged period.
DH worked in a similar setting for about 5 years and it would get him down really badly. Some afternoons I would have to pretty much counsel him when he got home from work as he'd be so depressed. He now works in a blue collar industry and couldn't be happier with the change!
Can you get a role in another department where talking to people is not required? I'm sure you've acquired great experience & skills in that job which will be desirable to a range of other roles and industries.
If it was me, I'd be looking at other avenues, maybe a little counseling via your company for the time being?
Good luck moving forward
