I’m tripping on shrooms and I feel horrible

I have no clue what to do. I’m so scared and I genuinely have no clue why. Are shrooms just not right for me? I’ve done lsd before and it was really fun but this feels nothing like it. I’ve never felt so inconsequential and small in my life. Im pretty sure it was only 1 gram. How do I stop myself from doing this from now on? How do I feel better?? I just want to feel happy. I just want to be happy again. Please help me
