Hello future Bella!
This is only 2 years ahead but I assume you're going to be a completely different person honestly. There is so much that is bound to change and it exciting to think about. So here's what I think you're going to be like but please don't beat yourself up about it if you're not.
I'm hoping you have finally learned to have a better relationship with food - no binging/correct portions etc. and that you've lost weight and kept it off and can finally be comfortable in your skin because you deserve to feel your ABSOLUTE BEST.
I also hope that you feel confident in your career path. I'm hoping you're in the HCDE program as of now, but if you're not you'll make the best of it. and if you're not in engineering... well that kinds sucks but hey at least you're not stuck doing something that most people find boring.
I hope that you've found success in school, and hopefully a job/internship/research opportunity that has made you level up a bit as a person.
I hope that you're still involved in music, I'm sure by now Lake 22 is having some issues or is completely disbanded due to members going off to college. Even if it is disbanded please remember how passionate you are about music and never let go of it. I don't care what anyone says you are GOOD AT IT. and people will benefit from what you create so don't let it go.
I dont know if you've had much success in the dating world. At the moment COVID is making it VERY difficult to be involved in any of that. I just went through a MASSIVE tinder phase and it resulted in... being single. The phase is probably not over but thats alright we'll see what happens. I just hope that you are doing alright in that department and that no one broke your heart. Just remember your worth and remember you should never accept less than what you deserve. You are a queen and any guy would be lucky to have you, so if whoever is in your life isn't treating you like gold, drop them.
I hope Dad is doing alright... I'm gonna do everything I can now to make sure he is.
Overall I hope that the work im doing right now to level myself up and improve myself works out for the long term. I have to ask - are you still besties with Natalie? what about Olivia? I can't imagine Natalie isn't your best friend forever honestly.
Anyways know that past me is very very curious about you, and remember that you are loved and if things have gone downhill you can ALWAYS TURN IT AROUND. You are worth the fight.

I love you,
Bella.
