marijuana & medication..WORSE NIGHT OF MY LIFE!!!?!

I take medication for Bi-Polar,depression,schizophrenia,anxiet… I smoked some REAL GOOD WEED CALLED "DRO", and I felt like **** afterwards, I thought that my sisters bf and his friend were talking about me, since my life is so screwd up like they were making fun of my past, I felt so angry inside but I had the control no to say nothing stupid to them, I just said that i Just don't feel right, I want to go home, I was repeating that, so When I got home, a lied on my bed and I thought I was dying, like I was having a heart attack, my heart was pounding really fast, so today I feel depressed and still a little down and angry because of what they were talking about me, even tho it was not pointed directly at me, still thought it was, and they were just laughing. Please help me, I don't want to think that my sisters bf i making fun of my past, I don't care about his friends that I don't know, and how can I make this stuff go away, because I still feel a little bit like last night.
