I,ve been getting lessons for 7 years, with 4 different teachers, i am 25 and i still feel like i don’t know what to do, i haven’t been able to improve my singing, i still don’t know where my voice  is comfortable, i haven’t improved my range, i don’t know how to get a good tone in any register, i don’t even know if i have a correct breath support anymore,  i still dont know hot to get ti mixed voice,i even feel like i lost some techniques and notes due to teachers contradicting what i should do. 

my first two teachers told me i may be a bass or low baritone, which made me obsess over vocal registers and scared of not being able to sing anything i like or sound like is my own voice (i have always disliked having a lower range, but even forcing myself to sing in those ranges, i feel it sounds bad and kind of forced) 

My range was around D#2-E2 as my lowest note without vocal fry i think (even though lately going there feels like i have to move my larynx lower and sometimes hurts, so maybe F2, but i don’t know which note could be considered projectable)and i used to think my highest chest note was G4, but it was forcing it and it sounds awful and without control, i think it would be E4 before starting to push i guess.  
I used to be able to sing up to A5, sometimes B5 in head, but now i feel lots of tension whenever i sing in head voice and i have a lot of issues to get past F5 feeling a lot of tension in my throat, even singing falsetto kind of feels like i have to push a lot to make a sound and sometimes my soft palate and upper neck hurts when doing trills or some head voice excercises.

Some teachers told me to belt, others to anchor my body and open ribs, others told me not to do that and sing high without pushing but like if i was speaking even if i don’t get any sound, others told me to not push a lot of air, others that it doesn’t matter…etc  
I keep trying to practice and do excercises, but i feel like i am doomed, i don’t know what the issues actually are anymore, i still feel like i couldn’t sing a full song with other people.

I have always dreamed of singing in a band or even just out loud without feeling bad or laughed at, every time i try to look up information about kinds of voices and tips or excercises to improve i just feel depressed for the rest of the day thinking of the times i have tried singing along to songs i like and how no matter what i do or what range covers, i cant sound well, even my parents have told me that i should stop wasting money and time on singing lessons and just practice guitar because i don’t sound any better. I know some people will tell me to keep singing if i like it even if i sound bad, but doing so just makes me more sad and discouraged about myself

I cant look for other teacher, its really hard to find local lessons where i live and im not comfortable with online lessons, but all the teachers I’ve had are professional singers and i know other people who have had lessons with them and have all improved compared to me, so i don’t think that’s the issue, so i don’t know if i should just stop trying and quit because i feel hopeless about my voice in general lately , i recorded myself the other day to compare it with an older recording to see how i sound after years of singing lessons and i felt like i still sound the same as then, which made me decide to post this here to ask for your opinions and insights on what should i do

I don’t know what to do anymore, is it time to quit?
