Need help with aerosol, meth, alc addiction

so I'm 16 years old when I was 12 I started smoking weed for fun w my friends after I had some issues with home life as I am in the system I started drinking, starting with just normal bottles of whatever which caused me to be moved to a group hom. Since it was difficult to get drinking alc I started drinking anything I could get my hands on for about a year, after that my friend told me about duster and I tried it and loved it which lead to addiction with that and over the years I started doing much harder stuff like meth and xans I od'ed on fent in February but it didn't shock me I didn't really care fast forward I'm 16 and have a job not because I'm ready for it but because I'm scared for when I get kicked out of the group home as the age limit is 16 if anyone has struggled with these addictions or have any support pls help
