You may picture detox as the first hard step before longer treatment begins. That picture is not wrong, but it is incomplete for your situation. Every body and every history is different. A qualified healthcare professional can help translate general information into something specific to you. Until that conversation happens, it is fair to hold your questions rather than guess at answers.
Some readers want to understand levels of care before they call anyone. Treatment can occur in distinct outpatient, inpatient, and residential settings. Knowing that distinction exists does not tell you which setting fits your life. It simply gives you a starting vocabulary for the conversations ahead. You still get to decide what matters most to you: location, support, or timing.
It is normal to feel uncertain about how much information to gather before reaching out. Some people research for weeks. Others make one phone call and go from there. Neither pace is wrong. What matters is that your pace feels honest to your own need for clarity and safety.
