I am glad you talked to your mom. What you are describing with the laughing about sui, mood swings and feelings of extreme restlessness was my experience on an SSRI when my pdoc told me it was a mixed episode. I thought it was just akethesia, but we figured out it was mixed episode. I suppose it's possible to have both at the same time, though. I am so sorry you are experiencing this all. I think you should really consider the hospital because group while group might help it will not be able to fix akethesia and you are discussing hurting yourself. If not at least call your pdoc ASAP and get their opinion and an emergency appointment. This is not something you should ignore and expect to go away. Please stay safe and get help.
