I'm pained to say I used DXM when I was 19 too. I was depressed (I'm guessing you were), and I'm pretty sure I developed anxiety and hypochondria due to it. There were times in my life when I was in a public setting and I suddenly couldn't function, so I had to lie down because I was convinced I had tumors in my brain or abdomen (lol). I've used additional drugs which I won't bother listing.

It's pointless to worry about the past. You can and should make the best decisions for yourself from this day forward, and it sounds like you're already doing that. You should be thankful you recognized your wrongdoing and stopped yourself from letting your self-harm spiral out of control.

I'm currently 27 and I'm doing really well in my comp sci courses. If anything, hypochondria helped me because I now exercise and eat healthier than I probably would have if I wasn't so worrisome.

24H Three sets of three.
25B Rotates clockwise. Top left and right are black while bottom left and right are white.
26A Middle line rotates clockwise. The pattern goes left to right across rows but continues on next row also. Lines attached to left and right dots rotate on that point clockwise. Transtion that is seen to the final square is also seen in top right->middle left.
27H Xor.
28G Three sets of three.
29E Middle is operator performed on left. Operator determines shape. Top row shows how the shape is influenced by the operator and the middle row shows how the rotation is influenced by the operator.
30A Middle is fitted into shape of the same type from left.
31D Sides are pushed out after being pushed in. Draw conclusions both horizontally and vertically.
32E Divide shape into 4 lines. Bottom right line is rotated once. Top left line is rotated once.
33G Three sets of three. Shape is a set, orientation is a set.
34G Addition. Inside circle is negative outside is positive.
35C Left is mirrored along axis in middle.
36F Three sets of three. Direction is a set. In each set each quantity of each square appears once.
37H >>9173705
38F Double arrows switch colours of sides. Single arrows stretch. The x operator rotates and the rotation is also applied.

Very cool posts, thank you all.

>You're not special, everyone gets this at some point. Drop the pretension and get on with it.
I was more interested in hearing other people's experiences.
Once in a while you happen to read very strange things on the internet.
My experiences are more artistic than useful.

>And if finding answers to society's ills isn't your focus, what do you live for? Why learn math or science?
Who cares about society?
I do math to feed my ego.

Some gaslighted people develop eidetic memory for conversations.
You can listen to perfect music in your head while you dream, if you cannot already do it while awake.
Your mind can create perfect images as well but it could be more difficult to summon useful information.
You should:
>Experiment with different drugs.
>Learn to lucid dream.
>Train your rote memory obsessively.
>Meditate.
Meditation helps you *relax* and tap into those abilities you have when you dream.
Lucid dreaming offers unfiltered, unlimited eidetic images, sounds, flavors, etc... but I haven't been able to look into real life information in my limited experience.
If you have the money you can spend them on nootropics. You can read about a handful of successful stories.
Then, say you have thoroughly understood and memorized a few books from cover to cover and can rehearse them in your mind while you do pushups.
Never done it with a whole book but in my case rote memory rapidly enhances my visualization abilities.
With meditation I can get into psychotic dream-thoughts after like an hour; very difficult practice.

Physics is derived from engineering.

This ones not quite humor but it is cool

post some challenge questions. I'll start:

Derive the Complex numbers from Real numbers without using the identity:
i2 = -1
In other words, that identity (or its dual √(-1) = i) should be a consequence of your formulation.
