I think what you said was ok.

and I have a different way that I handle such situations. that don't leave me questioning whether or not I did the right thing -

Usually when a friend tells me they have a problem I ask them first if they would like some information that I have on that and if they answer yes I give it to them and if they say no or have other excuses and reasons such as they dont want to go into therapy, read information whatever. I either say ok Im here if you need me and let it drop or I ask them if they would like me to - tell - them about what I know instead of giving them things to read, if they would like me to go with them to a therapy agency or group and so on. and again if my friends say no I let it drop by telling them Im here if they need me.
