Anu....I'm glad you posted and like you, I too feared that certain things would act as a trigger and might cause me to relapse. I went through some very frightening times but did come out sober and stronger.
You can do this and being thrown these issues can test our sobriety but you posted (which is huge) and we are here for you. You aren't alone.
I am keeping you in my thoughts and hoping all goes well with your appt.
Please stay strong.
