i tried to do it alone for many years. the difference was this last time when i reached out for help. so far, it's been my longest bout of sobriety.
i don't know if you can do it alone. but why?
think of it like networking. you'll gain resources, advice, references, and support by talking to others. you don't create your own "luck" in the workplace by holing up on your own. you can do your own research, but it takes twice as long as meeting someone who's already done the research and learning from them.
the decision is yours and you will find the right answer for you. you are on the right track by coming here and by seeking answers to your questions.
keep coming back!
