Hi step,
Thank you for sharing, sorry about your situation.
There are many ways to share your esh. The big book step 12 does call us to service, but there are more ways to be of service than to sponsor per se. You can make coffee at meetings, chair for a month, etc. that's service. Coming on here and sharing in the hopes of helping others is good too.
Keep coming here, keep sharing. In focusing on yourself and your recovery, and being open, you will help others. When the time is right, and it's evident to someone that you have what they want, someone will come to you.
Attraction not promotion.
Good luck, thank you for sharing.
