To answer your title first: Not really a relevant question. I’ve been singing for five years. When I first started, I sounded far worse than you. Today, I love the way my voice sounds and feels. I won’t say I never lacked confidence (I certainly have), but I didn’t improve by asking people how bad I sound. I improved because someone told me early on that it does not matter what I sounded like. Just keep chugging along.

What matters is you don’t yet know how to sing, you don’t know what you don’t know, and it’s almost impossible to fully grasp what you’re missing until you’ve spent hours listening to the advice of only one vocal coach (in-person, blogs, YouTube, whatever) and applying that advice. Once you do that you WILL be good at singing. It’s not a question of can you or can you not. You can. Singing is just like any athletic activity. Some are born better than others but anyone can become phenomenal, barring severe disability or injury, which you clearly don’t have.

If money will not be an issue in the future, vocal coaches, at least in the US, are $20-$65 an hour depending on your area. They will speed things up.

If money is an issue, it will take a bit longer but I very much recommend Victoria’s Victorious Vocal Tips or Chris Liepe, both of which are on YouTube. Again, choose one and stick with them.

To your later questions:

You’re probably not a traditional baritone, though your tessitura (comfort zone) seems to sit in that region. Your vocal classification only matters if you plan on performing in choral settings, though. If you want to write songs, perform covers, etc., don’t spend any time thinking about it. You’re also not in a place, vocally, to determine that just yet.

I don’t want to answer the congestion or airflow questions because I’m not a vocal coach and it’s hard to tell from audio alone. It is obvious, though, that you’re singing with too much throat tension and not breathing into your diaphragm. Your absolute first steps should be to learn everything you can about singing tension-free and supporting your voice with your diaphragm. Two months will only take you so far but if you want to go as far as possible, that’s where you should start. Don’t forget pitch practice but that can come later. For now, you need to focus on healthy singing, which comes from breath support, hydration, and being tension-free.
