Stress and hair

[spicy12]

i have 4 questions below: im 22 years old and i was very stressd and anxious for a period and it was even hard for me to eat sometimes, and one day i shed much more hairs than normal (probably telogen effluvium, but it only lasted for 2 days and stopped) its been a few months since then and im still a little stressed but not as before,i think i can see that my hair is starting to go back to itself but now i see thin and thick hairs combined on my head, i know hair loss due to TE is usually temporary but i dont know if the thin hairs i see are the hairs i shedded before due to TE and they are growing back, or is it just that some of my hairs are now thin. plus i used to have a very oily scalp and suddenly it produces much less sebum causing my hair to dry. btw im taking finastride for more than a year and it works just fine, no side effects. my question are: 1: i wanna know if my hair will grow back and is it the thin hair i see today? 2.why is my scalp's sebum production so low now? 3. my hair is now dry and has weak appearance, it looks more flat than before.will it grow thick and look good again? i have a well balanced diet and i exercise.
