i'm sorry you feel so alone. i had to respond because at one time in my life i felt as i had no one who truly cared about me. what i discovered with time was that my friends are my "family". it took time to find those special people that loved me just for being me. there was a lot of experimentation at first cause i didn't know what qualities in friends i was looking for. by helping others and taking the focus off myself i found that i was surrounded by people that valued me for just me being me. it's difficult to describe the process i went through but a T really helped me through this period. today i have a family that loves me conditionally. however today i have friends that love me unconditionally.
the first thing i had to learn to do is to love myself for who i was. if there was an area that i thought needed tweaking about myself i did it in therapy. then i was really able to find true joy and make the valuable friends i have today. if i didn't love myself how could others love me?
another thought: do you think you are looking in the right places for friends?
i hope these thoughts will help you and i wish for you all the joys i have found in the friends i have now.
