I'm sorry to hear you feel that way, It's not a good feeling to carry on your own for to long, so the fact that you tell someone just anyone about it is a start. You should start doing something about that feeling of loneliness before it consumes you more and more. I know it might be hard at first, although i don't know the exact reason why you are feeling lonely, but most experience a strong feeling of loneliness if they spend to much time alone.
If you are at home by yourself most of the time, that surely can provoke such feelings. Try your best to meet up with people, if not friends then family etc. It will also help i think to spend more time outside, and to pamper yourself (work out, eat healthy etc.) doing this you get a better confident, and after a while hopefully you'll also feel less lonely. But most important (as mentioned) try try try to be social in any way you can.
If it is uncomfortable to put yourself in social situations, start out by messaging or joining discussions with people here - that will at least be a start. I hope you will find some sense of belonging here with the rest of us wrongplanet members.

the problem is that I'm on one side want to meet/talk with people on the other I don't, 'cos it hurt! I'll close the topic 'cos it's not possible to get a solution in my problem on the forum. It does not solve my problem. it is necessary to take action. Thank you for helping to understand that I need to do something in real life.
