21 and I feel no different?

So I turned 21 about 2 weeks ago.
I feel no different. Big whoop. The only thing I've had to do was beg people to come out with me, because apparently no one wants to go out. Which is surprising. People keep bailing on me as well. It sucks. I made plans with one of my friends to go out tonight since I have nothing tomorrow except one class, and for once I finished my homework ahead of time, and she texted me to say that she wasnt feeling good. Just yesterday she was talking about how excited she was.
Meh. I was really sad. I was looking forward to it all week.
I guess I'm just used to people going out all the time when they can, i.e. my friends in Cyprus go out to clubs and bars all the time. It's so different here.
I've been having really stressful, long, exhausting days this week, running around from class to lab to work...I don't want to do it anymore.
I'm done with school. I just want to enjoy myself. Is that bad?
I was accepted for my study abroad program for next semester. It will be fun. Just have to wait a couple of months.
I have also applied for 3 internships for the summer. Two at this company, I have one phone interview tomorrow morning (which I am nervous about) and one next week. And the other one, the application isn't due until April 5th, meaning I won't know for a long time if I get it. I hope I get that internship because it will allow me to do my thesis research during the summer for 8 weeks while getting paid, so I can be all set for when I return for the spring. It ends at the end of July too, so theoretically I could also go to Cyprus, something I wouldn't be able to do if I got the job at that company. I don't know what to do if I get three different jobs.
I want to work and make money, but I also want to have a summer and just relax, go to the beach, see my friends abroad, and get tan.
I work a lot during the school year so I feel like I deserve a break.
But I hope fall semester will be awesome, as I will be in ENGLAND!! I cant wait! I hope to be able to travel to Paris, Amsterdam, maybe Spain?? It would be amazing.
And one of my friends goes to school in the same town of the University I am going to be attending, so I will know people and know that I will have a good time.
Tomorrow I'm going home for Spring Break. I wish I was going somewhere warm to tan. Instead I will be sitting at home all week. It's ok, I will get to spend some time with my family and friends.
Maybe next year?
