How do i improve my play from Black?

I have  a USCF rating of 1808 ( provisional after 5 games ). I seem to do quite well as White and i enjoy playing as white. I scored 2/3 from WHite and just half/2 with Black. Not only bad results, i feel kinda bad while playing from Black. Is this mental ? I don't think its my openings as i have played many different ones, same result.  Please help me.......

Find one basic opening reply against e4 & d4 and stick with it for at least a year. Only when you play a system for a while will you know where your problems lie.

Which openings should i play though? And just in case i stick with an opening for at least 10 months so it can't be a problem of "changing too often ".
