I felt the same after my break up (19 F). He has buddies and a close family, and I'm very introverted and my family isn't as emotional as I am... or as most people I should say, and I only have one friend from grade school halfway across the country. I kind of had my moment of panic, thoughts of dying alone and feeling like there was no one out there to get comfort or reassurance from. I felt (and still feel) lonely and scared,.... BUT it also kicked me into gear once I got over the initial fear, and I signed up for some new classes and activities! I met a bunch of people from different age groups, and even though I din't make any long-term friends (yet!) I felt good knowing that it was possible for me to socialize again, and that I could make people laugh, or be useful and encouraging to others, while they helped me back! It's been great, and I feel less alone every day :) If you ever need someone to talk to, I'm here to listen. If not, then best of luck to you, it will get better! <3 Nobody deserves to feel alone.
