I can relate. I feel like this fairly constantly and have for decades. I'm not a very touchy person to begin with, also have trauma and body dysmorphia. my go-to line as an excuse has always been "I'm not a hugger"/"words of affirmation over physical touch".
I love that it's seen as a lot less strange to 'send' virtual hugs, or just send along that sentiment right now, though the reason obviously is distressing.
