Hi whenever I fall through there's a sense of guilt so strong that I get depressed and feel like this will be the cycle of my life constantly falling through any advice on this?

i know exactly how you feel, most of us do .All i can tell you is what i experienced when i looked at each fall compounded on top of the rest of them,it feels like a huge mountain of guilt crushing me. with each cycle making me feel like im stuck in never ending loop 
one thing that helped me is that hashem tests us ive found that the test here is not if we will fall but the test is will we let it take us down my father had a saying what doesn't kill you will only make you stronger each time we fall and just move on without getting dragged down we won we are stronger look at each time as a battle that if you get shot and get up and continue fighting you won
prepare yourself mentally that when you fall you will go do something right away to get your mind off of it
we love you
you are strong
we believe in you 

Another option is to figure out how to stay away from the first sips.
Not to say that it's in your control, but as much as anything is in your control, it's how to stay off the roller-coaster, because once you're on, it's a hundred times harder to get off mid-ride.
