how to lose weight

shhh

this is embarrassing but i am 16, 176lbs and 5’3. i want to lose weight and body fat. i know the only way to achieve that goal would be to work out. i am ashamed to tell anyone. please leave workouts i could do in my room. i don’t have much equipment. my mom has a small gym in the house but i don’t know when to use it or how to. i want to better myself. it’s november now and i want to be able to look different next month for the holidays but that’ll be hard. i want to look good by summer time. send suggestions on what to do please.
