Last night I was looking through something of mine and noticed something strange about them so I did a reality check (the nose one) and realized I was dreaming, so I got really exited but I tried to control it but I woke up after like 2-3 seconds. Was this really a lucid dream? (Ive never had one before) and if it is, will it be easier to have one from now?
Title edited for clarification. 
It was a lucid dream, but getting too excited tends to cause a wakeup. Congrats on your first LD though! Just try to keep yourself calmer in your next LD. 
Congrats! 
Yes. It was your first lucid dream
In next LD’s focus more on controlling your emotions. You now know how LD look like, so when you will start another LD, take a deep breath and say to yourself: “I’m now dreaming and I’m gonna stay in my dream”. Then you can do whatever you want but remember to plan everything before going to bed. It’s crucial to make a list like: firstly i will go to my school (A) and then look for my teacher (B) and talk to him ©. Think about that activites cause it will be much easier when you will ld again. AND if you start LD do NOT say to yourself that in that dream I want to do ABC. No, that would be a big mistake. Just think like A -> B -> C. Hope it will help you
