I was in exactly the same spot a month or so ago before I cashed out a large chunk of my BR. I kept moving up and getting killed, it happened 3 or 4 times and really dented my confidence but I kept at it and it worked out eventually.

There's definitely a difference but I eventually went on a massive heater and ended up recouping my losses and hitting something like 30% ROI. If you're a good enough player it'll sort itself out and you'll be fine.
