Tightness in throat, unsure of next step

Hello Camille! First off, thank you for all you do for the singing community. I hope you are doing well!

For a while, when I sing for more than 1-2 minutes, I start to feel my throat getting "tired." I really don't know the word to describe it, but it almost feels like my throat starts getting tight. I have to work harder to get the same tones/sounds to come out. It don't notice it every time I sing, maybe 50% of the time. I believe it happens mostly when I sing near the upper range of my chest voice or the lower range of my head voice.

Also, about 4 months ago I finished the 30 day course...I haven't really done much else and don't know where to start. Here is my current level: I can match probably about 2/3 to 3/4 of the notes of a song without it sound "off." My vibrato is hit and miss (mostly miss, it's up to chance that it will happen, and when I focus on it, either sounds ok or sounds pretty shaky), and my vocal agility is very poor. My goal is to be a solid singer, I don't have to be spectacular, but I've always wanted to sing and would love if I could somehow sound good one day. I just don't know what my path is to get there. I don't have a lot of time a day, but of course, if I have a solid understanding of what I need to do I can make time to do it. 

Hi, Jared! Thank you, and thanks for being here. 

You might consider a private lesson so that Abram or I can hear and see where you're at. But in the meantime, I recommend you follow the steps in this article (and replace the 30 day course with any other lesson series on the website, unless you want to repeat the course). 

Most important is that you're warming up daily, working on songs, and training your ears!
