Proove them wrong by your actions and focus on you now. You and your path to sobriaty.
If you can avoid those people then do so. If not give them some boundaries if you can.
Ask them to support you instead.
For me cravings where better to handle when I kept myself busy. So in the beginning of my recovery I walked loads. It’s still a big part of my recovery, because the work in recovery never stops. A hot shower ore bath helped me as well.
Here is a thread I made years ago with the things that I did to get sober. Pick out the things you wanna try yourself. Recovery for me was and is trial and error. It’s not a custom fits all beside some big simularities. So try to add stuff and keep what work and trow away the rest. You will end up with your own sober toolbox 
2 years sober and what helped me to get there: I’m still sober, more then 5 years now. Not to bragg but to tell you it can be done.
Choose not picking up the first one, because we deffinitely can’t say no to the second one 
You can do it, see you around!
