I'm stopping drinking alcohol; it only makes things worse.

Hi, I suffer from anxiety and panic attacks. At some point, I discovered that alcohol makes it go away temporarily. For the last three weeks, I’ve been drinking alcohol almost every day—and quite a lot of it. I’m stopping now, but I’m worried that withdrawal could be dangerous. I don’t even want to Google it, because that just makes me more anxious. It’s been about 12 hours now; I’m just really nervous and feeling very hot. People say it only gets dangerous if you’ve been drinking heavily every day for years, but others say even three weeks can be risky. Can anyone give me some advice? Or has anyone else been through this?
