I think this song is about addiction and how it can let drugs control your life.
Nur für mich bist du am leben
From knowing an addict i can certainly say that they only live for the high that drugs give them
Ich steck' dir Orden ins Gesicht
Drugs are proven to be physically harmful to the person using them and in the case of people addicted to meth they sometimes pick at their faces which gives them the appearance that metals have been poked in their faces
Du bist mir ganz und gar ergeben
Same as the first line
Du liebst mich denn ich lieb' dich nicht
Addicts love the drug they are addicted to even though it is harming them
Du blutest für mein Seelenheil
A drug's purpose is to be used and metaphorically bleeding (or physically depending on the drug) will happen when the drug's purpose is fulfilled
Ein kleiner Schnitt und du wirst geil
The body starts to release chemicals as soon as the it knows the drug is entering the body to prepare it for the good feeling
Der Körper schon total entstellt
Most drug addicts such as meth addicts and crack addicts don't look after themselves and eventually look disfigured in a way
Egal, erlaubt ist was gefällt
Ich tu dir weh
The substance is harming the user
Tut mir nicht leid
It has no feelings and cannot feel remorse for its harm
Das tut dir gut
Through all this physical harm, the user feels like they're on top of the world.
Hört wie es schreit
Some addicts who are off of their substance can compare the temptation of drug use to the drugs calling out to them, just asking to be used
Bei dir hab ich die Wahl der Qual
There isn't a drug in the world that doesn't have any bad effects that contrast the feeling the user feels
Stacheldraht im Harnkanal
Leg' dein Fleisch in Salz und Eiter
These two general torture lines talk about how the substance is tearing apart the body of the user
Erst stirbst du doch dann lebst du weiter
Some drugs like cocaine or meth are known to cause people to OD through cardiac arrest, but if help arrives in time they'll be defibrillated

Bisse, Tritte, harte Schläge Nagelzangen, stumpfe säge
More torture
Wünsch' dir was ich sag' nicht nein
The drugs have no control over how they are used and won't "say no" to the "request" made by the user
Und führ' dir Nagetiere ein
Du bist das Schiff ich der Kapitän
Drugs are usually the ones in control of the addicts life
Wohin soll denn die reise gehn'
The drug will take the user to whatever "high" they want
Ich seh' im Spiegel dein Gesicht
