Hi. I, too, am sorry you feel that way. And yes, I also share the same experience. But one thing I realized is that people who know us actually love us. We just don't give them a chance to show that they do care for us. Everywhere we go, we meet new faces and these encounters give us the opportunity to know other people.
I think you have to love and feel good about yourself because when you do, you allow others to love you, too. Sometimes, we are the only ones who are making our lives too difficult. I'd like to go back to what I've mentioned earlier, "We just don't give them a chance to show that they do care for us". Why is this? I think it's because we are blocking their way towards knowing and loving us. You are feeling alone and lost because you are allowing yourself to feel that way.. We are humans and being so means being lucky that we were given the power to think of what's best for us.
I know this is really hard to overcome but I believe there's a way out of this. Feel good about yourself. Busy yourself with doing the things that could help you achieve your fullest potential. Be the best person you can be because life is too short and unpredictable. We never when it's going to end.
I hope this will help you. Pardon my grammar, though
