There are two points I would like to make that might help you. The first point is one of the blind perspective. Instead of seeing your latest circumstances as "bad luck", suppose for a moment the possibility that the universeis working on a grand plan where these "unlucky" times are needed to get you to a wonderful place that you can't even think about with your limited prospective of the total situation.
Second point is a general rule of thumb for almost all magical workings: The most powerful spells are those you create yourself and put the most energy into. Go all outon correspondences, pick your own herbs and explain to the live plants your goal and intensions, plan your spell out and think about all the details of it throughout theday(s) and focus on literally feelingyourself build up power and being more and more charged and then when the spell is done, feel the release of all of that stored upenergy surging out of you to go do your work.
Good luck and I hoped this helped. It has worked wonders for me for years.
