The only time in my life that I didn't struggle with debilitating anxiety, lack of direction, confusion about life, lack of motivation, etc... was after a huge DMT trip. Not a little CEV inducing one, but a 'multidimensional beings have ripped my consciousness from my body and the information of the universe is pouring into it and, oh great, now I'm dissolving into the fabric of space-time, good bye me, see you in 15' kind of trip. I can usually keep the good vibes going for ~2 months or more before I obliterate myself again. The things that I've learned are...
That if I can overcome the anxiety to destroy myself, and if I can do that, I can overcome social anxiety and make friends.
This life is incredibly short compared to the infinity it's suspended in.
If life is short I need to make the most of it, and enjoy it. I need to learn as much as I can about this existence before it's over (like a trip,
)
Part of learning is exploring others' perceptions of this reality, by making friends and being extroverted.
Exploring hyperspace makes me want to explore this reality. That's where motivation comes from for me.
More directly, it's helped me control my thoughts. I was actually becoming aware of a room sized bubble of anxiety ridden thoughts and over awareness that was floating around my head. It was heavy and it made me actually tired to carry it with me. I've been able to pull it back down inside of my head now, and I feel lighter and more open. I still live in my head, but it's much smaller and there's more air to breath now.
Also, I know the feeling of slacking, not using any talents, beating yourself up over it, feeling beaten up, and then especially not feeling motivated because you've been telling yourself how much you suck.
Prove yourself wrong. Isolate those thoughts in your mind. Itemize them, then for each one that pops up counter it with something awesome about yourself. If you have a talent or hobby, painting, writing, reading, etc., when those thoughts pop up immediately start doing one of those things. Don't give it time to justify itself, prove it wrong immediately. It is wrong.
Another crazy thing I noticed is those thoughts come with a tension and a dark feeling on the right side of my head and neck, and the loving entities I meet in hyperspace stand on the left side of my head almost each time. I just had that thought, and it seems weird lol.
