Useless

-I feel useless.
Every time I try to do something I end up doing it wrong.
Every time I try to fix something I make it worse.
Is not there something I can do well !?
or I'm just a good for nothing but the bunch.
I feel useless in front of that person.
That despite what I am, sees something that I can not capture in me.
That having ruined things still trusting me.
I do not really understand how you can see something good in something that is not good for anything.
