Yeah I'd say I'm fairly stable, mentally that is. I did get in fits of depression this past year during school, more than I had previously in my life, but it was never very serious, I never sincerely contemplating suicide or hurting myself. As for bipolar tendencies, um no, my moods are generally pretty stable, I don't just switch moods.
As for the environment, it wasn't really stressful I wasn't too worried about getting caught or anything. But my one friend who wasn't high (because he didn't smoke this time) kept telling me to be more quiet or else I'd get caught and he said he was going to go to sleep soon because it was like 3:00 am, and I started feeling real depressed when said these things cause I wanted to stay up and didn't want to be alone. And also while I was high and getting emotional, he kept jokingly saying, "I never gonna get you high again" and this made me burst into tears and display the previously mentioned symptoms. But it wasn't just his comments, cause even depressing songs got me real down.
And no, I haven't gone through any trauma recently, family deaths or anything. Basically, I can see where all this emotions came from, but I just don't want to be like this next time; I just want to be super chill and happy like i thought I'd be.
