Feeling discouraged...

With a million questions all starting with why, why me, why is this so hard, why isn't this positive yet, why isn't this working , why is this so much money. Ice had two failed iuis, the second one took a toll because it was much diffferent from the first and the numbers were all great so I took some time off , plus I wanted to survive the holidays without the added stress. So going back into it now I feel so discouraged , any words of advice ?
