ConEd Bill is out of control

Just got my Con Ed bill for Jan-Feb and it’s $551. I’m in shock, I live in a tiny studio but I do have central heating. Is this normal?

Contacted support and was told there was no way to reduce the bill but I could enroll in budget billing, has anyone tried this?

Edit: I left my window open while traveling for a couple of days, which most likely contributed to the hike. Taking my L but it still sucks
