This is a very brave expression of lonliness. You wrote it just the way it feels.
Lonliness could be in a crowded room...if you feel alone inside. I know just how you feel because this is my life too, except for some online friends. You can even be married but if two drift apart and feel unwelcomed, misunderstood, unloved.....the same feeling can set in. Every day becomes a lonely rainy day. What you said about friends is true also....you care very much but feel let down and the truth is you're really alone inside amost all the time. To keep from feeling totally heartbroken and invisible, the only thing I can say is to treat others with even more care, respect and kindness and some will come back to you. You will experience hurt when you try harder but you will also feel more moments of sharing and grace. Eventually, hopefully, you'll find one who wishes for nothing but to be by your side who loves you. Thank you for sharing your difficult feelings and know that you are not alone in them. Some days are so hard you wish you could just give up....but don't. Sometimes we learn our greatest lessons through our own personal struggle with lonliness and sadness.

oh hun, i'm so sorry.
i wish i could help. =(

jim is right, stay strong.
i too felt lonely at one time in life,
i cried for 2 years straight.
i hated everyone, but i was wishing and praying desperately for someone to rescue me.
in the end tho i rescued myself.
i'm glad i did.
i found a strength i never believed i would ever have.
and i'm learning to love myself more and more each day.

you can do it.
be brave hun, have faith.
and trust me, no one can rescue you better than yourself because
only you truly know what it is you need.
