i'm left handed when i started playing i just borowed a friends guitar (right hand guitar) i didnt even know they made left hand guits back then. i've tried to go back and mess with a left hand guitar a couple times but it just feels alien to me. i would sugest one of 4 options
1. just learn to play right handed.
2. get someone who really knows what they are doing like a real guitar tech. not just a friend that plays guitar, to set up a right handed guitar to be a left hander
3. buy a real left hand guitar.
4. theres really only 3 options

1. cheapest and if you are a complete beginer this should not be that hard. if you think about it, the chording hand usualy does the most complex work.
2. a bit expensive but should work, but anytime you get a new guitar you have to get it reset up, and if you are ever jamming with others you wont be able to share instruments
3, if you are determined to go lefty this is what i'd recomend.
