Just got out of detox I'm a fety and heroine

Just got out of detox I'm a fety and heroine addict things aren't going as planned I went to a Suboxone clinic from detox and they had started me on Subutex before I left detox well the Suboxone clinic that I was told to go to and was cabbed to was closed so I'm supposed to go their today at noon to get started on Suboxone I have no ride their and 4 hours ago I copped some fety well I haven't done any but it's calling me it's over a hour walk and it's raining really heavy I want to make my appointment because I'm so fed up with using I literally been up all night because I didn't get my dose of Suboxone like I was supposed to I feel like I'm in withdrawal my skins on fire and I'm super tired anyways I have to be resilient and make this appointment so wish me luck that things turn out better than they have been
