Siddharth,
If only you look around you will see what Baba has done here at this very forum with just one post from you.
You say you looked for loving, guiding support, a teacher, a helper, a friend... just anyone.
If only you read a few posts after that you'll see - someone called you friend, beta, someone who guided you, someone who tried to restore faith in you, someone who asked you to keep hope and hang on, someone who showed you how strong and better you are, someone who somewhere gave you the answer to your 'why me' question, someone who is praying for you, at least 2-3 people who understand 'its frustration' not hate... people wanting to understand you and shower you with love, support, prayers and blessings.
Now, please re-read Anupamji's post.
People hurt us Siddharth. They hurt us all the time. No one on earth said all would be good to us. In fact, theres not a single person on earth who will not hurt us at some point of time in life. We are all human Siddharth. Its natural. We hurt knowingly-unknowingly. I'm not saying its ok. Am saying its human. Those who caused hurt did the best their brains could think of at that point of time. May not be right, but people always do the best they can given the circumstances. Many a times it turns out to be wrong, hurtful to others, selfish and deciving. But thats all they could do at that point of time. Their soul was not mature enough to understand and feel your pain or the consequences. And the account of their actions is for them to settle with God and themselves.
What is it that we can do now... for ourselves? Forgiveness Siddharth. Forgiveness is the best gift one can give oneself. As difficult and hurtful as it may sound (and trust me it is difficult)... forgiveness is the only way out! Your not forgiving people will not make any difference to them. But it will to you. Until the bitterness remains, you're going to be in pain. You've already been thru so much. Why nurture and pamper the pain more by remembering all those people? Is it worth ruining your life and peace? Don't u seek peace? Then let them be. Just think of them as immature souls and forgive them and move ahead in life Siddharth.
God doesn't make a looser out of us Siddharth. He makes us fight and fight and fight till we get better and better and stronger! They say Siddharth, God is more interested IN THE GROWTH OF OUR SOULS THAN OUR CURRENT COMFORT.
Maybe thats why...

We're all praying for you Siddharth. We are all here a complete family. And we are not letting go of you. Each one here wants to see you stronger, wiser, happier and at peace. Each one wants you to be an inspiration for millions of others who maybe going thru a similar situation as yours.
You asked why Sai Baba does this to you? Maybe He wants YOU to be that one inspiration for millions who face many, many, many troubles in life. No one is a looser in life Siddharth. No man, however worse the situation can be one.
ONE CANNOT LOOSE WHEN ONE HAS GOD WITHIN. LET THE GOD WITHIN YOU WIN SIDDHARTH.
YOU CANNOT BE WEAK SIDDHARTH... YOU ARE THE STRENGTH.
FOR THERE IS NOTHING YOU ARE MADE UP OF BUT THE LIGHT OF GOD!
Please tell yourself the minute you feel low.
THERE CAN BE NO DARKNESS AROUND FOR I AM THE LIGHT!
THERE CAN BE NO HATERED, FOR I AM LOVE
THERE CAN BE NO LONELINESS & SORROW, FOR I AM BLISS
THERE CAN BE NO WEAKNESS, FOR I AM STRENGTH
THERE CAN BE NO DEATH, FOR I AM LIFE
Life is about choices Siddharth. START AFRESH AND CHOOSE LOVE, LIFE & LIGHT!
We are all there with you... through this entire journey. No one is lonely, for we're all on the same path... with the same goal... reaching God...
Om Sai Ram
