Welcome Silvy
It can be very overwhelming at first but it really does get better.
There are many recovery options available. I read about Rational Recovery/AVRT when I first quit. For many years I've been depressed thinking about the past and anxious about the future. Since then, I've learnt about urge surfing and positive thinking/mindfulness which is very much an ongoing process for me and learning everyday but it does help. I've learnt so much from SR and try to live for 'Now' Easier said than done sometimes but heading in the right direction
If you like reading-2 books which have helped me immensely are "The Power of Now" Eckhart Tolle and "Think Right,Feel Right"- Dr R Isett. Jon Kabat Zinn is also very good,all recommended to me on SR
