is it worth to take xtc?

I am 17y/o and i'm experienced with weed and alcohol, and i also did lsd once which was amazing. I'm really into the psychedelic effect of drugs, but i want to use those very rarely because i want to keep it 'special'. Now i thought acid was really intense and i don't plan on taking more for a long time. During this trip i felt like a little kid again and started getting quite sad about my drug use; i have some potential and i feel like i'm throwing it away by doing dumb stuff at such a young age. I haven't smoked weed in a long time as well because lately i've been getting a bit anxious when i smoke sometimes.

I'm a bit scared of xtc. My friend and i have 1.5 pills lying around somewhere but i don't really like the idea of her taking it because the lsd made her depressed again after a month in which she finally felt happier.

What are the effects of xtc like and is it worth taking? Do they affect your mental state even after the effect has worn off?
