I feel guilty cutting of my friends. I been reducing my time spent with them more and more. It seems that my life has improved a lot more because I am not influenced by them.

They will ask to hang out and I will, but when I do the drug and alcohol abuse is disturbing. We're all college students about to graduate and the habits they've develop are the opposite traits that I want for myself.

I want to cut them off completely but I'm not sure how. This may seem stupid but I feel I might regret it and possibly become depressed. I just want to know how to live without people I've been really close to, it's not like I'm a psychopath.

Any advice on how to cut them off or ways to deal with this issue is appreciated.
