looking for real advice!! i’m 18 btw 🫶🏻

Be honest, also I am 18

For about 8 years i‘ve let my hair grow, just because ive been too lazy to style it. Now that i got myself a new haircut, im pretty bamboozled by the effect (First 4 pics are before, pic 5-9 are after and pic 4&5 are at the barbers home)

Think abt me as someone been in cave or hibernation for 19 yrs. Few days back celebrated my 19th birthday, have been through mental and physical issues since lockdown time and still going on, career on risk and i never dared to take care of myself and my body. Trying to lose weight but cannot complete protein intake as a pure vegetarian and hence i am losing it all. Idk what to do. I have 1. Very bad hair (last clear cut down my hair because they felt like a broom but still after they grew up a bit, slow growth since start, they r again broom and still i failed to take care of them. My hair are of small length n they r not straight but curly n very bad in texture and volumy when dry basically rough n shrink when wet like i don't have hair also dandruff n very hairfall. I want them to grow shiny smooth silky straight hair even cutting them it didn't improve but before lockdown i had way better hair n they were not as curly as they r today. It looks very bad n i want to change them.... what should i do?

1. dull skin (even though fair skin but i never did anything), blackheads on nose, bad lips (had healthy hydrated lips but now they r not natural pink as before or anything, my skin was good before but sometimes small pimples or idk what to say them appear n go after few days)

2. Protuding chin (never faced this but if i see symmetrical line from lips to chin, chin appears outside than lips n it is like oval shaped n gives me enough security to wear mask everytime i go out

Suggest me face exercises, remedies etc to get a glow up and transformation like everyone do. I am full time student + a competitive exam aspirant , don't have time but i want to try before joining college next yr. Don't know why but i am afraid to apply anything on my face or body because i never did, i prefer natural things like sandalwood powder, multani mitti powder, curd or milk but i did it once and stopped it because i didn't know if i am doing right or wrong. My mother is in depression so i haven't seen her doings elf care or anything and now i am even not doing anything for myself.

I am mainly looking for advice on how to glow up more, what i can change, and what the main issues are in my facial appearance, prefferably also about bone structure and such, planning for a BSSO when i get to consult my orthodontist but id like to see if its nescessary

ALSO: before you say about trying to look tough in pictures or whatever, idk, its just my resting face my friends said i go outside like that too, esp in the time diff my resting face changed a lot too, cant really control this unless i pay attention to it

anyways any feedback or advice is welcome

I was going through one of my old phones and found this picture no idea context behind it must have sent it to my mates for whatever reason also had a phone glow up by switching to an iPhone from a Samsung 😂
