For me too, since I started my recovery a few months ago, tephilah has become much more meaningful for me. I really pay attention to the words, especially the chasimos of the brachos, each one affirming that HaShem is the benefactor for every aspect of human needs. At shacharis, I include a personal tephila in shomeia tephilah, "l'hachzireini b's'shuva shleimah liphanecha," to affirm every day that my recovery is only by the will of HaShem.
Also, I try to go to minyan regularly (at least once a day) also, which works very well to combat isolation.
