<human>: Give me the gist of the text in a nutshell

Sorry about this wall of text. It's been years since I've had any crushes whatsoever aside from my current GF (Zoe). Zoe and I go to different schools around 20 minutes away from each other. She has a busy schedule as do I, so we don't get too much time together. The time we do get together is usually filled with homework. We're pretty much polar opposites of each other in both interests and personality.

I recently met this new person (Stacy) at school who I instantly developed a massive crush on. Worked together with her once or twice on some assignments over the past few weeks and it literally was one of the best experiences I've had in a while. She seems to have many similar interests as me, and seems pretty great overall.

Now I crush hard on people. I remember when I first developed an attraction to Zoe, it was pretty damn similar to right now. It was hard to focus on anything without thoughts of her creeping into my head. This couldn't come at a worse possible time however because I need to focus on my schoolwork and work. I don't have the time or the energy to draw all of this stuff out for months.

I can't even think straight enough to write this thing. I enjoy Stacy's company a ton, and love talking with her and the such. She's much more outgoing and gets along with my friends (same friend group), while Zoe has always been super shy and reserved around them. If I ask my friends, 9/10 would probably tell me to ditch Zoe and try my luck with Stacy. I'm a little hesitant on ditching a decent relationship however, for something that may or may not work out in the future.

What should I do? Should I end the relationship with Zoe and try with Stacy? Should I stay with Zoe? Should I do the jackass thing and try dating both? I'm honestly at a loss right now and unfortunately feel that I have nowhere to turn but the internet. I know that none of this probably makes any sense b/c I can't organize my thoughts with all this junk.
<bot>: Crippling crush on someone, no idea what to do, need to do something asap so I can stop being crippled.
