Hi and welcome to the forum!
I would suggest starting with a low to moderate dose of mushrooms.
Make sure that you are in a comfortable environment and that you feel good, as in not being emotionally loaded.
Read up on the experience or/and start a post in the mushroom section of the forum.
I would suggest tripping in an environment like from the comfort of your house, alone or with a very close friend, or having discussed with a close friend that he/she be available at the time of your journey, to be called and come check up on you in case you feel the need. I would suggest turning off phones, don't answer the door.
It is a journey in yourself.
That's why I personally like to trip alone or with a very close friend and by that I mean not interacting with anyone else during and/or shortly after the experience.
Be sure to take out some time for it, best would be the day after as well, as a psychedelic experience tends to be very intense and the mind needs some time to 'root' again if you will.
Have a nice trip and be sure to let us know how it went!
