@sussan, These days there are no true friends again. Rather you should have a business partner, with that you'll be able to share ideas and and attain higher positions.

There has to be someone you feel safe to reveal your weaknesses to (not necessarily the opposite sex)

You can always talk to God anytime, he's always there to listen and heal your pain. Revealing your weakness to a friend is dangerous, you're only giving them ways and techniques to use against you tomorrow. Am very sure you've not experienced betrayal before, cause if you do, you'll probably get the whole point.
