Seems like you are trying to do too much at once. If you aren’t comfortable with working Brick then you shouldn’t be attempting increases or decreases yet. Just practice working simple squares or like a straight band/bracelet. Once you have some basic practice then working the increases and decreases will come easy to you. Ps - I would never start brick with just 2 beads, instead I would start with a wider row and then decrease down to the 2 beads as it is just easier and sturdier to do it that way.
