Welp, never thought I’d be on Reddit saying this. But I need help.

I never liked alcohol but began to drink twisted teas when I was around 18. I’m now 22 and drink 5-7 days a week. It was already 2-5 then I lost my 21 yr old brother last month. Now I just want it constantly. My biggest worry at this point is I drink 2-4 24 ounce cans of twisted tea daily. 60 grams of sugar per can sometimes more if they’re flavored, they also have 60 mgs of caffeine. What are the genuine health risks after heavy use for an extended period of time. I still function fine, go to work n do my stuff. But how long is this able to go on without health issues starting, believe I already have hemorrhoids have been avoiding the dr. I am able to see I have an issue. I don’t like any other alcoholic beverages other than those. My brother left behind a 2 year old son and I want to be there for his son and be a good role model im on my way to being a full time ups driver and I’m spiraling. Someone just say some piece of advice or anything. I don’t know at this point what I want or need. Im a hard worker and a decent person I feel like overall but this is sucking me in.
