Feeling increasingly paranoid lately - is my BP getting worse?

I have been feeling increasingly paranoid lately.
I have always been a little paranoid about things, and like I have mentioned in another thread, I feel like I need to change doctors and readdress my meds as I am noticing other quirks about myself as of late.

I am on 900 Lith ER, 200mg of Lamictal, and 300mg of gabapentin (which I feel does very little for my anxiety)

Anxiety is a more recent "discovery" as I have just been noticing that it's been getting worse the last year. My sister helped me to figure out that I had a mental "brownout" last year, that was surely anxiety related as it was a high stress situation.

So maybe this increasing anxiety level will help figure out my paranoia.
I hear noises at my back door, and I will get up and look out the window. If I have to leave my dogs overnight at my place I will be worried about my place catching on fire, if the power goes out and the heat/ac goes out.
I smoke in my place, and have for 6 years...not a ton, and I take measures to ventilate very well, but...I am always concerned that someone will complain, leave a note, etc.

At work places, if I feel outcast, which happens on occaision, god forbid two people glance at me and are laughing about something, my mind will go to "are they laughing at me about something? Why?"
The intelligent side of my brain says "you are crazy" but I can't help or surpress the actual feeling.

I am overcareful with lots of things - just seemingly paranoid.

I am not sure how much more detail is relevant to this post or not, so I will stop here.
I just feel like I am progressing to the point of being the crazy person thinking that everyone is out to get him. It really feels like that sometimes.

So maybe this is a venting rant, but in either case, could my bipolar be getting progressively worse?
I am turning 30 later this year (eeeks!) and have been diagnosed for, I think 4 or 5 years.

Any advice would be helpful.
Thanks

I have heard that bi-polar can get worse without meds, also your body can become used to the meds and becoming more resistant?However as you age your body chemistry changes, so maybe it's time for a med adjustment?

I think so.
Last night ened up being terrible for about 25 minutes, I was deathly afraid that someone was going to break into my place and I even brought a knife to my nightstand (for protection). It was really strange.

Paranoia is a sign of mania and possible psychosis for me. Worth reporting. I take the same doses of lithium and lamictal as you btw. No gabapentin though.
