Hi Ryan well done on embarking on your journey towards recovery. The first step is to take proactive actions to signify that you truly want to quit forever. Self-exclude youself from all online sites you use or might use. Install betfilter/gamblock on all your devices as added security.
You cannot do this alone and whilst the forums offer great support, seriously consider about attending GA and/or disclosing your problems to a close relative/partner/friend. Emotional support is key to recovery but ultimatelt it is up to you to do the hard yards necessary for quitting. Make no mistake it will be a tough road ahead but if you take it one day at a time and truly want to quit, you can turn your life around.
