I am so sorry that your feeling this way. Sounds like you have had it really tough.
It isnt fair. Everyone needs at least one person to care about them.
I feel so sad reading your post.
Maybe you will find someone soon. I hope you do.
This is a very hard thing to do if you feel you have never been loved but could you try to love yourself?
Once you love yourself you will find yourself attracting love and attention of others.
I know it is a very hard thing to ask if you havent experienced love but please try.
Do you have a therapist. Is there anything you can do to try to make friends? Any group activities you can participating or even church if you are religious.
The gym is a really good place to meet people and make friends. Do you go to college or work?
