<human>: Background info: I've been binge drinking for around 7 months, and then 2 and a half months ago I decided to drink double as I usually did and quit, but I started feeling ill the next day. I think it was a mild withdrawal, lasted about a week or so. Then I had a mild gastritis shortly after. The first few weeks were pretty awful. However, since then, I've been feeling off.

I'm feeling light headed and dizzy all day, when I stand up my vision blurs and goes darker a bit, almost like fainting I guess. Nausea is a bit better though. I don't have any energy at all. Kinda feel like my stomach is still upset a bit. I have had a bit of anxiety once or twice, and have been thinking a lot more about existential stuff.

My family has been saying it's all in my head, but I'm not sure. Maybe since I'm not numbing myself with alcohol I worry more about life and death and the sort, but that still doesn't explain the light headedness and feeling like a total crap.

So do you guys think it's medical related, or am I just bonkers? I probably should visit the doc soon. I've been putting it off in hopes I'll feel better, but it's not happening apparently.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Light headed, dizzy, nausea, no energy, mood swings for 2 and a half months. Gradually better, but still feel like crap. Any advice is much appreciated.
