To the overthinker,
You are more than this. Every single second that you spend thinking about what could be happening, you're missing out on things that are happening. Stop thinking of worst-case scenarios. Half the time the things you think up are so unrealistic it becomes silly.
Texting someone first won't result in World War 3, it just won't.
Don't discredit yourself. You have a lot to offer the world. The fact that you are very good with making up scenarios in your head means that you're a good storyteller, and people love stories.
Yes, it can be scary to speak up, speak out, or to tell someone how you really feel. You never know what is going to come from the other side, but you can control what comes from your end. Don't let it be radio silence. Give people an opportunity to get to know you. If they like you, that's great, if they don't, you'll meet other people who do. Hiding in your room wishing your life was great but not having the guts to go out and do stuff isn't living.
Take it from me, I spent the first two years of college constantly getting out of commitments I made with potential friends because I was scared, and one day I realized that I don't want to live my life in fear anymore.
Do I still have mental battles with myself in order to convince myself to go out and do things? Yes.
Do I have moments where I completely blow things out of proportion and makeup stuff in my head that isn't even close to the truth? Yeah, I do, but I don't give it the benefit of having control anymore.
So put yourself out there. Text that person to hang out, go to that event you're really excited about even if you don't know anyone, try that new food, talk to that person you sit next to in class. I can't guarantee that it will be a great experience, but even if it's not, take notes. Learn from it. You'll have a better experience next time around, but if you don't get out there and start living your life to the fullest, you're gonna regret it.
Sincerely,
Someone who has been there and understands.
