Your only 18 ... your supposed to feel like that... But you are living in tough times, and I sorry for that, but your not alone at least. The tricky part is hooking up with the others like you. You see then sit at home, and join web sites like forums to talk to other people.
Now if you can get them to come out of their holes and actually meet each other that would be quite a feat !!
You see man... I'm 48 years old, but have been living in isolation for 7 years now. All my family is gone and I only leave once a week to get my mail, and maybe some milk and eggs. So I wish I had some answers for you man, I really do, but I seem just as lost as you.
So tell you what .... Just relax and tell us what's going on... I think you will be surprised just how many people here not only understand, but are going through the same thing. You might even meet someone you get alone with pretty good.
Do you spend allot of time at home, or do you work, and go out doing something like exercising maybe ??
I have allot of hobbies to keep me busy, and calm, take my mind off my problems and exercise it too. So tell us just what's going on... maybe we can suggest something... but if not we will listen.... Deal ?
