Okay so I have horrible mood swings...high highs where I feel like I can do anything to low low where i can't even leave my bed cause I'm so depressed. I almost lost my job because of this. During these lows I want to die (attempted to kill myself before) and I really need to know how to get help seeing as I'm in one of the lows now and want to die. I'm trying so hard but I just can't deal with it. I have no health insurance and I need help. If it help I'm eighteen and live in the u.s. I'm more then ready to die. Please don't say it's hormones. I've been dealing with this since I was 5. I always carry a knife on me. My dad makes me because of where we live and where I work. I'm afraid of what I will or won't do with it. I use to hurt myself and almost did today. I stopped but I can see that wont work anymore. I know it will be expensive but I think at this point I need to be hospitalized. How do I go about this? And what's wrong with me?
I got diagnosed with schizoid personality disorder along with antisocial personality disorder symptoms the psychiatrist said I should schedule weekly sessions with him but I don't have the money or health insurance to afford it if I leave this untreated will it get worse? Or progress further? I feel stupid calling and asking especially talking about it on the phone since the rest of my family doesn't know I went in to see psychiatric help also should I let my family know? I brought up the topic to my dad and he stood firmly by his word that there's no such thing as mental disorders that theyre just demons in people's heads and that if I pray hard and long enough it will go away (my dad is a pastor) so if I tell them they'll just judge me, and say its not a real disorder and to go to church. I'm not sure what to do now?
where are the answers?
I asked a question , how and why you chose your agent and company , to buy your car insurance ? ( Still open) All I have is people who are somehow connected to the insurance companies , asking for your company. It seems that every insurance company formed a "band manager" , made with people and customers , which is expected not only to pay your premiums on time , but is also expected for samples of a " gang " the activity, pushing force other people to join your company , mostly up and down swering your insurance is cheepest and the best ! I wonder if they are paid or a discount for doing this? Is there anyone out there that is not connected to an " insurance band " that answers my question? apprentice
