Honestly that sounds like a major overreaction. People in Phoenix have been dealing with the heat forever and they still buy groceries. If a single comment from one person makes you rethink your whole budget, maybe the budget wasn't that solid to begin with. You gotta stick to your plan and not let random opinions throw you off.
Ngl, benlewis has a point about sticking to your plan. But honestly, sometimes a random comment from a real person hits different than just looking at your own numbers. It can show you a blind spot. If your budget feels shaky after one chat, maybe that feeling was already there and the comment just made you see it. It's not always about being weak, it's about getting a new view on your own situation.
