Hi Jesse
I'm full of sympathy for you! Neptune square MC is tough when you're younger. It gets a bit easier with experience! You have the advantage of knowing astrology, and that you're navigating a particular kind of energy.
All the previous advice is very important - stay away from negative people, stay away from drugs & alcohol [anything escapist that blurs your lens on life], don't over-idealise people in intimate relationships, strive to be clear & transparent with people, focus on working for a higher ideal / humanitarian organisation if you're not poring your energy into something creative. If you're feeling completely lost, go find a good charitable cause & pour your energy into volunteer work until you feel a clearer direction.
Try not to flip-flop in multiple directions continually, while being escapist & feeling sorry for yourself!
This is the voice of experience
I have the same tight square from stationary Neptune in 12th house square MC conjunct Moon....
Actually our charts have interesting cross-overs.
I also have the Sun / Mars combo, so i expect you to be very high energy. I've seen a number of charts with Mars conjunct Pluto of mountaineers & people with the most extreme endurance [the mountaineer Peter Mathiessen who wrote the book on buddhism called 'the Snow Leopard' has it]
MC in Libra, conjunct Venus & square Neptune, i'd expect to either pour a lot of energy into trying to make other people happy [a superb negotiator / mediator], or something creative like fashion or the visual arts.
You have a 0'30 trine between Jupiter & Uranus, so you can't be that unlucky.
You also have Uranus conjunct North node [which i share] in Capricorn 1st house, also conjunct Neptune & square MC/ Venus. This is a very revolutionary energy. You will not tolerate the status quo
I also have the Venus / Uranus energy. It pushes me to be very avant-garde in all areas of life - business, intimate relationships, creative expression.
You have a very exciting chart. Hang in there! You'll grow into it! In the meantime don't waste time with any of the rabbit holes mentioned in the first paragraph. If you're currently in a very conservative environment, i suggest moving & putting yourself amongst either an international charity, or an avant garde group of creatives
Your Saturn return in 2020 is going to be an absolute doozy...at the same time you have progressed Sun conjunct AC, the transiting nodes conjunct AC/ DC, and transiting Pluto, Jupiter & progressed AC in a tight pile up
. Your sidereal Solar Return for that year also indicates major action
