I am left handed but learned to play golf right handed. Should I switch back?

Hi. I am (severely) left-handed (as in I can barely use my right hand for anything) and I started playing golf when I was about 9-10. I have been living in malaysia since I was about 3 and at the time I started golf, my Dad couldn't find a lefty set my size, so bought my a righty set.

My relationship with golf has been an on-off one and I did drop it at about 11 or 12 (by this time I had proper sized right-hand clubs). I am now 15 and have picked it up again, and it has been going well (for my standard :S).

Recently I picked up my dads old lefty golf clubs (he is right handed but playes all 2 handed sports the lefty way) and tried swinging them in my garden. At first it felt a bit unnatural, but after a while I felt as if I could put a lot more power into the swing compared with my other clubs as I can't hit too far with my right handed clubs.

Should I make the switch to left-handed clubs as I suppose I am still a beginner and I think I would probably perform better playing the left-handed way?

Thanks!
