Given all of the information you've provided us, I've changed my opinion. I think your type is ESTP or ESFP.
An Se-dom, like an ESTP or ESFP, will have an affinity for fun in the present moment in a real and direct way with the environment. They're also known to have an agreeable and easy-going disposition. Under stress, they typically become overwhelmed, tired, negative, worried, and withdrawn.
ESxP's will project inferior Ni. It often emerges as intolerance of ideas, theories, and free-flowing musings of people who prefer intuition and read between the lines.
As for hobbies, it's not uncommon for Se-doms to be attracted to the mysteries of intuition; especially Ni (their inferior function). Systems that deal with inner forces, mysticism, and extrasensory perception can be alluring to Se-doms.
Auxiliary Feeling for ESFPs emerges in their focus on friendly and compatible relationships (and teamwork). I don't think you're an Fe-dom because you said you don't always connect well with others, which I interpret as you're not especially energized by social connections for the sake of them. At the moment, you seem to be more energized or have more of an interest in Se-related activities.
You indicated in your younger years you thought school was pointless. With that in mind and considering all of the confusion you appear to have with the direction you're headed in your studies, and dropping out recently, I've come to the conclusion, you have trouble with long-term planning, commitments, intuition, and understanding how the present moment fits in the bigger picture. In fact, it seems to trigger a stress response in you, which I mentioned earlier. It seems like you feel the information you need to make decisions won't be available until the future is now, which doesn't happen and throws you for a loop.
