It's great you're young and can catch this before it progresses any further. If you're drinking because you need to in the morning that's not a good sign. If you drink while being responsible for a child that can lead to trouble too. Even if it doesn't interfere with your finances the money spent on beer could benefit someone (college fund? family vacation? food pantry donation?) in a tangible away instead of pouring it down the drain.
If you found SR you must have concerns of your own. You'll get lots of help and support here-welcome!
