I think it's natural to talk about T ,it's a huge part of your life right now. It's natural to want to talk to those closest too you as well, but if your mom doesn't get it, she doesn't get it. In hindsight you could have left the " my T says " part out and just mentioned how your mom was hurting your feelings by trying to minialize your feelings regarding the bugs. My partner reacts the same way, so ive learned to drop the "T said" or i act like his suggestions were my idea... It works well, because she doesnt "get it". Don't spend this glorious day fretting about all this, be kind to yourself today.
