Yes. Change is hard. Change is very scary. It's absolutely normal to be scared of the unknown. If we could just magically pop out of one scenario into another one of peace and serenity, who wouldn't do that? Unfortunately, if we want change, we have to do the work. Just like your husband has to do the work if he wants recovery, so do you. Nothing changes if nothing changes.
Lumping everything you need to do together in a huge pile can be especially daunting. Maybe if you made a chronological list of each step you need to take, and then cross it off after you do that, it will look more manageable. Everything is a process, and if you take things a step at a time, it will all work out.
