Office work fucked me up

[Ataol]

Six months ago—before my internship started—my posture was excellent. My face was actually starting to improve, but once the internship began, my posture deteriorated because I was sitting in an office chair that was terrible, with the computer screen positioned below eye level. Consequently, my face lost its definition and started to sag; it feels like my features have shifted downwards. Now that the internship is over, can I fix these issues and get back to how I used to look (specifically reversing the facial sagging and drooping)?

Yes you can fix it

But how? I used to do a lot of exercises for my posture, but I don't remember any of them.
