I'll keep this short. I'm in a work WhatsApp group. Lovely colleagues but feels awkward because I'm the only person who rarely contributes. We use an internal chat system at work, so whatsapp a bit pointless in work hours. I'm a lone parent, so busy and barely have time to myself. I hate texting at the best of times. Genuinely feel like I'm becoming the antisocial one who doesn't communicate other than in work hours. It leads to people asking if I'm ok, when actually I find the constant comms overwhelming. Anyone else feel like this? AIBU? Should I contribute more?
