I am 14 (although im turning fifteen on 4/20. Yup its awesome) and would say that age doesn't matter although like me, your brain is still developing and that could be negatively affect you. Its how you act. I used to be exactly like how you describe but after I got over it, it was a lot better. Here's some things you should fix
Very bored of life
Find a hobby. Drugs are temporary. Dont use them to kill boredom. Use them to learn about yourself (with drugs like psychedelics) or just to enhance life sometimes (alcohol at parties; weed with friends once in awhile; MDMA for special moments)
I dont have much going for me
Drugs wont help
Depressed
Drugs and Depression will not go together. That is how you get an addiction and you certainly do not want to use escape drugs
No friend Networks or nothing
Join a club or a sport
No realistic aspirations
Work harder. Its not going to be easy
I'm insecure and I'm really, really confused and scared about life and the future
Don't be. I used to be too. Once I got over my anxiety I learned something. You need to Enjoy Life instead of wanting to waste it on drugs just to speed up the time. I feel like you just want an escape and trust me, psychedelics will not do that. You have to be ready for them. Thats why I stopped taking them and I am waiting until im ready and in a great mood. Psychedelics will just enhance your insecurity I feel. Although it can be blissful, its very, very scary.
I've listened to Joe Rogan and Duncan trussel talk about Psychedelics, and I feel its something I really want to try
Thats awesome but like my brother's friend told me, psychedelics are things you do when you are at the peak of your life and want meaning. That age is 23-25 (he said that more jokingly but still, thats a great age)
I'm worried if I had a trip, I might hurt someone, which really scares me, or say something stupid.
You should be tripping alone or with a trustworthy friends and make sure your parents will be out the whole time. Also, remember, you wont hurt someone while tripping but yourself. This is all about you. It can seriously hurt you if you are not ready like it did to me.
All in all, I would say to enjoy life first and find a hobby. One hobby I used to enjoy is coin collecting and although it sounds stupid, you can make money from it at the same time as youre doing it. I totally recommend just going to a bank, buying ten dollars in pennies and just searching through them and keeping the copper pennies and any wheat pennies. Its always fun and it actually gives me a buzz haha. But yeah, psychedelics will fuck you over if you are not ready. Get a hobby and start enjoying life without drugs and then you will be ready to start using psychedelics!
