süchtig vs unabhängig
independent
'unabhängig' and 'süchtig' are clear opposites when it comes to dependence. 'süchtig' means that someone is strongly dependent on a substance or behavior and finds it hard to get away from it. Here, 'unabhängig' means that someone is not determined by or dependent on something. 'süchtig nach' can also be used colloquially for a very strong desire. In that case, the contrast is less medical, but the idea remains similar: 'süchtig' shows a strong attachment to something, while 'unabhängig' shows freedom from it.
süchtig
Mein Nachbar war lange süchtig nach Alkohol und bekommt jetzt Hilfe.
My neighbor was addicted to alcohol for a long time and is now getting help.
unabhängig
Seit einigen Monaten fühlt er sich unabhängiger von seinem Handy.
For several months now, he has felt more independent from his phone.
