How do you trust yourself??!

that question is bugging me..i'm struggling whit self trust.

it makes me sad that eventhough i was aware of it i cant do something about it. 

I always seek for other's affirmation that i can do things..

Im afraid to trust myself.. I might get wrong.

but im taking actions with of course by seeking other people's help.

i've read an acticle about selftrust but i wasn't able to finish it but its a good read though.
