Is it possible to have panic attack and flashback together?

I think what I am experiencing is a combination of the two. When I get triggered and it can trigger without warning just like that ... just a moment of weakness or a thought flashing by and then it gets me and I am inside a panic attack/flashback.

Then I get extremely extremely embarassed and ashamed but I don't get any visual or picture in my mind. Then I hide from people as they are sensing my vibes and forces and they can sense that I am radiating some kind of force or energy. Also the shame makes me paranoid and I feel I come off looking suspicious.

Then I hide from people and have to get to my apartment as soon as possible, then I get under the blanket and I start sweating, even if I remove the blanket and start breathing heavily. I get nauseous too and my thoughts are going crazy 3000 miles per hour.

During the panic attack and flashback if I get a thought and that is scary then that thought keeps running through my mind and I can't get rid of it even if I try to. Like if I think I am going to get nauseous and throw up. So then I keep thinking that until I get nauseous. I can't stop the thought.

Then I take a lot of sleeping pills to numb me or break the cycle of the thoughts by making me really dizzy. Works sometimes, sometimes don't.

Then I keep breathing heavily and my legs start shaking and I feel my neighbors can sense me so I hide in a corner of my room under the blankets and I keep breathing heavily and getting nauseous and sweating and my thoughts going round and round and my stomach full of fear and terror. The terror is rising up from the bottom of my stomach and rising up and holding me in its grip.

Then after 4 hours or terror it calms down although I have had them for 48 hours in a row once too so it can be very long like that or shorter.

Can anyone relate to this? Let me know.
