Yes, what you are doing can definitely be part of anxiety. What you are doing and what I did is called rumination. That means you go over things in your head over and over and over causing great fear and anxiety.
I was a worrier since first grade. Worried my mother would die, and she ended up living to be 89! Then when I got to college I was worried something would happen to Family members back home none of which happened. Then when I got married and had kids I worried about the kids going to friends houses in case something bad happened. I worried about the kids driving with other people in case there was an accident and on and on and on. It basically tortured my mind over and over all for nothing! My kids are all grown now and doing very well.
i'm trying to make a point that what we need to do is live in the present, live today none in the past and not in the future. Once today is gone we will never get it back. The past is memories in the future is unknown. Worrying is not going to add a day to your life so it is useless! I got to the point where if something happens in the future then I'll deal with it at that time because absolutely none of what I worried about actually happened!
worry is based on fear. When fear takes a hold of us it reeks havoc on our lives! We have to be in control
FEAR stands for false evidence appearing real. So when we worry about something happening to a loved one, that worry is based on nothing, on a non-reality that we are making up in our mind!
Believe me, the what if thinking can make you really sick. It did it to me and now I have terrible generalized anxiety that pops up whenever it wants to. Please don't do this to yourself. you are young, you have a future, And I'm sure your family would want you to go to college and focus on yourself at this time so that you can have a great future. The odds of our worries coming true are practically zero.
there is a great audio meditation found on YouTube that I think could really help you! It's called Detachment from Overthinking. Another one is called clearing subconscious negativity. Put in some earbuds, lay down and listen. It teaches you how to separate negative thoughts from yourself.
also there are some other great audios on anxiety, depression, etc. many to choose from. I listen a couple times a day.
you're a fighter for yourself. Be determined to stay focused in school because you need to do this for yourself! Don't let fear take you over.
when you get a negative thought such as worry about family, don't try to fight it off because that will make your anxiety worse. What you do is simply calmly acknowledge that you have the thought. Then Imaginate it floating off on some dark clouds and dissolving in the sky. Do this every time you get a negative or anxious thoughts and eventually your mind will automatically get rid of that thought.
if your having a real difficult time, speaking with a counselor who specializes in anxiety can really help! It helped me a lot. They can help you get to the bottom of why you're feeling so anxious and give you tools to help you.
your studies are very important for your future! Doing this for yourself does not mean that you don't love your family.
if you can ever pick up a book called mindfulness it's an excellent read and shows us how to get rid of unwanted thoughts and develop a life with peace of mind.
I wish you the best and remember, our thoughts are not a part of us, they are separate because the mind very often will go to the negative if we let it. You don't have to let it. Thoughts come and go all day long but you can control them by acknowledging it, then watching it disappear. I do wish you the best at college you will be fine! 😁
