Hello! Oh to be 20 again! :) not sure if you are in any meds., or not? At 20 I wanted to runaway and live on the beach! :) it was just a fantasy, and we all have them! You're at an age where a lot of people don't know which direction to go! Ask God to show you the way! He will! Do you think your moods are very high most of the times? I would definitely tell my family Doctor about this, so he can check your blood work! When our blood is out of whack it can cause our thinking to be crooked! Lots of exercise, healthy foods, and 8 hours of sleep really help. I take vitamins too! So, yes I can understand how you feel, but if you get to the point you're making some questionable changes, please tell your family, family doctor or a psychiatrist! You will find your way!!!
I think at 20, it's common to not know what direction you want to go in life, or who you are. It's a lifelong journey. It's important to ground your decisions in logic though. Running across the country to meet someone you've never seen, when you think it through, isn't good judgement. Just check your thoughts and try to maybe write a journal, decide about your interests, talents, etc. and try to pursue them instead of being lost in flights of fancy. You can always imagine, and then work toward a goal. That just means you are a creative thinker.
You may not have depression yet but I worry that it may be coming. I used to live my life like that and it was fun but when life slowed down and I had to reflect I starting coming up with regrets that ultimately led to depression. The main thing is not to think there is something wrong with you. Instead just wonder that there may be something wrong with the rest of the world. I am diagnosed as bipolar but I cannot prove whether there is something worn with me or if there is something wrong with the rest of the world.
