Depersonalization, schizo, or spiritual?
Your story reads like someone who has a pain and uses Google to diagnose your illness. When you get to the bottom of the illnesses, (where they list he worse-case scenarios) you say, "Yup. That's what I got, schizophrenia..."
There could be a few things going on. Right now, we are in the middle of many planets in Retrograde, along with the Moon having lunar eclipses. Since everything is energy, this change in planetary energy is heavy and dragging all of us down. Have you ever heard a police officer say, Oh, it's a full moon and the crazies are out? Something as simple as a full moon does that, so you can imagine what planets in retrograde are doing to our energy. Mercury comes out of retrograde on the 18th, so things will soon start to lighten up!
It could also be that you are being psychically attacked. I'm not sure whether it is human or supernatural, but I would assume, first (so we don't go to the worse-case scenario, again) that someone is psychically attacking you. You need to cleanse your apartment and set a feeling that you want for each room-bedroom, peace, living room, joy, kitchen, happiness...whatever feeling that you want to have living there.
Then, search your friends, co-workers, neighbors, family, and feel where you think the attack is coming from. Who wants you to not succeed? Who is jealous of you and your life? Get into a meditation and ask Archangel Michael to help by surrounding you with a protection cloak, ask him to place a protection cloak around your apartment and also your car/bike. Then, ask him to stand in front of you to shield you from any incoming bad energy.
You can also call on Azna (Mother God) to protect you. I use Azna a lot when trying to keep my grandchildren safe from their psychopathic Dad. Your Higher Power (whatever you call him/her) and a boat load of angels are here just to protect you. Call on them. They are standing by waiting for us to just ask.
I'm sending you lots of love on your journey.
