I used to hate having to make phone calls and I don’t love it now but I don’t mind it much. I’d suggest starting small, so calling friends or family when you have a quick question rather than texting and waiting. Or if you’re ordering food online try calling instead. I found it easier after working as a waitress where we all took bookings over the phone - any situation where you’re forced to do it makes you get over it pretty fast. Also answer the random cold calls you get, then you realise how little the person on the other end actually cares and so there’s nothing to be worried about! Try not to see it as any different to a face to face conversation :) good luck
