Music is my life-long passion, and I took rock/pop singing lessons for some time so I feel I can relate to where you are and give some actionable advice. There is only one thing you can do: find a good teacher. You don't have experience related to singing, so you are not even able to diagnose what you are doing wrong and start working on it. You accidentally start pushing yourself into direction opposite to what you should be doing as I did at some point. Also, it's important to find a good one: if a teacher suggests something, then you try it for a few weeks and nothing changes, then maybe it's time to find another one. I'm not saying you can learn everything in a month, but you should at least notice something is changing and and understand what exactly you are working on. If the teacher can't explain what exactly you should improve (and how) other than "sound better" then likely it's not a good teacher. I cannot stress how important is finding the right teacher. Two lessons with right guy I found were much more effective than everything else I did beforehand for years (youtube tutorials, lessons with other people, trial and error). Don't try to be cheap: few weeks with someone who knows what they are doing can take you further than months with someone who doesn't (obviously I'm not saying that all good teachers are expensive and all cheap are bad. What I'm saying is that there is SO MUCH DIFFERENCE between an average and a great teacher that it's often worth paying for example twice as much). One more thing about teachers is try to get demos of their students and see if you like how they sing. Another piece of advice: get used to recording and listening to yourself. It's frustrating, but it's second best thing I did after finding a good teacher. I can't imagine making progress on singing without recording. And you can record yourself on a smartphone/laptop/whatever for practice purposes, no need to buy any audio equipment.
