You must know that everyone feels broken sometimes. It is perfectly okay to admit you're not okay. Expressing anxiety, depression, frustration, or any other kind of emotion is all part of being human. You are not the only one who can't decide which major best suits them. You are not the only one who can't pass an organic chemistry class. You are not the only one who has lost friends over petty behavior. You are not the only one who is sick of their job. You are not the only one who carries the weight of your family. You are not the only one who can't seem to let go of the guy who treats you like trash. You are not the only one who can't please everybody. You are not the only one.
In regards to friends: you win some, you lose some; personally, I say quality over quantity. When it comes to class or figuring out what you want to do in life: explore your options, take it slow, and don't let others influence your ultimate decision. To the guy that keeps sending you texts at 1 AM, but ignores you in public: "New phone, who dis?" And when it comes down to the most difficult relationship of all, your family: if they love you, which they do, they'll understand and most of all, they'll support you in all your endeavors.
Sometimes it takes a failed class, a loss of a friend, getting fired from a job, or a fight with your parents to someday look back and realize just why it had to happen.
Just know that through all of this, you are capable and you are not alone. All too often people say "Everyone is going through something," but astonishingly, we always feel like we are the only ones suffering. Going off to college, starting a new job, or even becoming a parent all have one major thing in common: finding yourself. Figuring out your new role and who you are can be challenging and too often people go in with high expectations. The best way to enjoy the journey and eliminate disappointment or frustration is to take it one day at a time.
The truth is you can't please everyone. You'll spread yourself thin and lose sight of who you are. When it comes down to it, you are most important. Your friends and family won't be the ones taking those classes or working in that field. You are at a point in your life where you have to decide what is best for you and your wellbeing. If that means changing your major, letting go of toxic relationships, or quitting your job, then do it! I support you and you'll be surprised as to how many others will as well. And do you know why? Because you are not alone. They understand and they are all battling something.
If you are ever feeling lost or alone, just remind yourself that you're not. I am here and I have faced many obstacles along the way. And I am 99.9% sure that your friends and family can attest to encountering some type of hardship during their lifetime. If you open up and accept the (perfectly normal) fact that you're not okay, you'd be shocked at how many other people share the same struggles and experiences.
