Hi Gracie! Your story is very similar to mine. At 19 i was also at my highest weight of 298lbs. Also 5'6". Have also had weight problems since childhood <3
You have made a huge step coming here!
These are the most important things I've learned in the time I've been losing:
Take it a day at a time. It's going to seem like a huge insurmountable task. Huge, yes, but definitely not insurmountable. Set yourself some realistic mini-goals for where you'd like to be at intervals, for example, on holidays and special occasions, or once a month.
The time will pass anyway. I've often thought to myself, "This is going to take me such a long time. It'll be years before I get there." The years will pass anyway. You can choose to make them count, though! I started a year ago October. I never thought i'd see my ticker as far down as it is. It really smacked me in the face today!

(in the best way!) In 3 months, in 6 months, in a year, you will thank yourself.
Look after yourself. Don't be at war with yourself. I know it's hard. I fought my body for over 10 years. Your weight doesn't define you. You are beautiful in so many ways! Pamper yourself with non food products. Moisturise your skin, use the special shampoo. Paint your nails, wear funky earrings! You don't have to wait til you get to your goal weight to consider yourself beautiful. Tell yourself that you look awesome. I sometimes hug my body and say "You're doing a great job, body! Thank you!".
Eat slowly. Savor your meals and put your fork down between mouthfuls. It's weird at first but I can drag a meal out over 20 minutes now.

My mum thinks I have "magic bottomless soup bowls"
You say you are embarrassed and scared. I totally understand. I was there not long ago. I still get there sometimes.
Remember that you are in control. It won't be easy, but it will be worth it!

I can't emphasize enough not to be ashamed of yourself.
Good luck and spend lots of time here - so many lovely people to help out!
Best of luck and lots of love
