I wouldn't worry about it, you've got to look after yourself cos your the only one that can keep you sober.
I was vey selfish in my early days of sobriety, I also reckon I was the most important person in keeping me sober, keep yourself feeling happy and well and your chances of making it through are greatly increased.
The other way to look at it is what use were you to people when you were drunk, I bet a sober you is a less selfish person than the old you wthout you realising it.
Bet you don't lie and hide things as much for a start.
Good luck with it all
