I gained weight after turning 18 and don’t know what to do about it

[6.4 looks]

I’m 6'4 and I weigh 89 kg now. Just a year ago I weighed 75.
Since I’m no longer a teenager, I can’t eat whatever I want and stay skinny.
My face looks bloated 24/7.
I stopped shaving and showering because my college is online. I feel terrible both physically and mentally because of this.
What’s the best way to get back to my prime? I understand I could go to the gym, but mentally I don’t really want to see all this people.
It’s a psychological problem i think
