Have your gambits set to the top one "HP <75% Cure" for two characters and the second one "Party Leader's Target > Attack". <--- Use this for the two support characters. Your main fighter Just have "Target: Nearest Visible > Attack".

It's good to stay two screens away from the save crystal, as this will respawn enemies when you replenish at the save crystal. Keep doing this, then when you are killing off the enemies a bit easier, change the cure gambits to "HP <50%" and carry on levelling. Personally, I did a lot of levelling at the start of the game on my future playthroughs to make sure I didn't fall into these situations, but gambit setups are an easy way to stay alive.

Always have healing/support gambits on top and offensive gambits under them.
