Scared to be sober again

Tomorrow is my 5 years sober from alcohol but first day sober from cocaine. I've been on a bender for a year now. My nose is on verge of collapse and need to heal to get surgery.

Being completely sober again is terrifying me. The loneliness, emptiness, and isolation. I'm dreading it. Sure, sobriety has some upsides but there's so many downsides when it comes to motivation, happiness, and will to live.

Sorry for ranting. I just need support. Hope that things will be OK. And I'll overcome this again.
