Definitely have a conversation with your GP and be really open with them about everything. Tell them about how things are so bad that only alcohol, weed and meds are getting you through it. Also go into detail about how the Jury issue is making you feel, ie keeping you awake at night, terrified every time the phone rings or a letter comes through the door.
Ask the Dr to help get the Jury issue clarified and dealt with so it's not playing on your mind anymore.
Good luck with it
