I don't always enjoy my parents company
Why do you not enjoy your parents when they are with you?
We talk too much and the conversations suck.
While it is wonderful to enjoy the company of one's parents it can get old, being honest with them might hurt their feelings. Be tolerant and make the visit shorter if you have to, but never tell them the truth about the visits. They will be so hurt and feel like they were a failure for you.
Yeah that's what I've been doing. They are very stressed currently.
I am really sorry you are in this position. I hope you guys can work things out and maybe try to talk about something you are interested in. It might help if you pick the topic to lighten the mood.
