I don't have any of these problems, but i'm a lefty player who has tried to play righty. This was mainly due to being skint at the time and there being no decent lefty basses available.
Swapping round and being comfortable with it will take ages. I'd been playing for five years on a piece of crap lefty when i tried. You've only been playing for a wee while, so it probably won't be as bad.
Getting a comfortable playing position is a good start. Then if you're going to be playing finger style, get a metronome and work on your plucking finger speed. When you're upto a comfortable speed, then start on your fretting hand. If you can stretch out to one finger per fret at the first fret great, if you can't just move up th neck , say to the fifth fret.
An example
Two notes, alternate plucking fingers. Fifth fret, first finger.
Two notes, alternate plucking fingers. Sixth fret, middle finger.
Repeat for sixth and seventh frets and ring and middle fingers. Then work your way across the strings. All very dull and repetitive, but it gets your head into the basics. Then you can start to apply stuff you've already picked.
Hope it helps...
Ps. I'm now richer and can afford decent lefty stuff, so i've been back lefty for some years.
