The business of recovery from any addictions can be very trying at first, but may continue if you settle in on an attitude or become fixed on a certain mindset that this is all there is. Thinking I can never have certain foods or go places I love because I could relapse into my old ways, or even I will never be able to hang with the "buds" because their influence is not good for me, can have a negative effect on sobriety. This leads to adverse thoughts and actions, and even worse, negative talk out of your mouth constantly. Life is a vapor, time has been wasted in selfish living, and a personal resurrection to the awesome wonder in life needs to happen. Returning to focusing on today, rejecting thoughts of what you cannot do, and being grateful that God has delivered you from a living death, will bring you back to thinking right.
This isn't in range for the newcomer to recovery. They are so focused on the impossibility of rising above their current dwelling place in life, the pain of trying to attain self-control enough to make one day, let alone looking to a better life. They don't think happiness can be found. The good news is, with a little patience, a little effort, a lot of prayer, and looking to others for help, just around the corner they may recover a belief in God, in self, and in living that transcends anything they have ever known.
Just to be able to laugh and enjoy time with family and friends, fellowship with others like themselves, and involvement in their church, giving themselves in service to others, may be an enigma today, but realized tomorrow. God wants you to discover the purpose He has for you. This purpose is packaged up with perks and benefits that will bring you something greater than happiness...joy. Joy will remain, while happiness is only temporary. The newcomer needs to do one other thing...change the way they talk. Talk faith, not fear. Talk belief, not doubt.
One final thought. Get to recovery meetings and just listen. I recommend going to different meetings where you will hear different voices in recovery, other than the same stories you have heard over and over. Seeing and hearing what God has done for others may bring you out of the fog into clear skies, so to speak. Your presence in meetings, whether you talk or remain silent, is a service to others. Any service you and I do seems to benefit us. If a doctor prescribed a medication that would make you feel better, and make life easier, we would take the medication regularly. Meetings and service work is that medication, take it as prescribed, it works.
