Is it anxiety or what? Not feeling right...

I am questioning the current state of mind I am experiencing. It is very uncomfortable. I feel lost in many ways and not certain what to do. My doctor has me on a combination of anti-depressants, anti-anxiety meds and Ritalin. I feel a very frightening/anxious feeling. My thoughts are not easily comprehending what is going on. Due to a medical issue involving pain, I spend my days at home, by myself, with very little structure. I find myself at times focusing in on my breathe and finding that I feel the need to blow air out of my mouth just trying to relax which I am not able to do well. I feel like my mind has a difficult time defocusing on the sensation I feel which seems to be anxiety. My thoughts at times also feel unorganized. I have a difficult time just settling on something or finding an interest in something. It feels like at times words are no longer meaningful and I cannot seem to lock into a focus. I also often feel a feeling as if I am falling or experiencing something mentally for the very first time which leaves me feeling somewhat scared.

Any suggestions or ideas as to what may help me relax and think clearer would be greatly appreciated.

Thank you,

ME
