Its a pretty common fear among the anxious, actually. Being with other people gives many of us a sense of reassurance and also keeps our minds busy with other thoughts instead of the fears about what is going to happen next. Its true that we need to overcome this fear/discomfort, and it will happen when you feel better (eg are less anxious). What gets you there, be it meds/therapy/time or some combination thereof, really doesn't matter, but when you do feel better its important to challenge yourself to face your fears, eventually they will recede. That can take time, and at least in my experience requires controlling some of the anxiety first. You definitely aren't the only one, lots of us dislike being alone. Hope this helps.
