Living with struggles

Hey I am new to this forum and I thought I would reach out to anyone who reads this. I have had an addiction for over 4 years but struggled to admit it. I always stopped when I could not afford to lose anymore but usually every 8/9 months the urge would take over and come back to take over my life. 

The last few months have been increasingly difficult and it feels like my emotions have been on such a rollercoaster. I let gambling fully defeat me as I lost money, started chasing, lost some more, took out loans to get it all back, I won most of it back but sadly by this time I should have stopped I was hooked, I was lost in this trance, it felt like a magnet was drawing me back to the casino the next day. It was that feeling of winning and I ended up losing it all. I had been dealing with this by myself for some time after I told my parents. I had begged them to keep this between just us and not to  involve my sister, brother or girlfriend. 

Fast forward a few weeks and within the space of one week I had told my girlfriend, my mother had told my brother and eventually I had to tell my sister. Its been 4 days since my older brother and sister had been told about my gambling addiction and they have not said a word to me. I understand they are in shock rightly so, but over the last week before they found out my parents and girlfriend (who is amazingly still with me) have not only motivated me but been there for me in order to get out of this. I am set on looking forward to my recovery but I struggle with the guilt and how my lies have affected those around me, it eats at me everyday. Mentally I am very strong but I feel like those around me supporting me will always bring up to a reminder of 'That money could have been spent on this or on that' 'Why did you do it wasnt you thinking' 'Are you even remorseful' 'Do you know how many people you have upset'. After having so long to reflect on this I know this all and I think about it everyday with deep regret. But can we ever move forward and recover if we keep reminding ourselves of what happened? These types of questions ring in my head everyday, on the way to work, during work/lunch, when I am home, in the shower everywhere. It eats me up slowly inside day by day, and I feel like the ones close to me should refrain from these questions as it only has an adverse affect on my motivation/ability to make the right steps. Am I wrong for this? Should they be always reminding me of what could or should have been?
