Can I have some advised pls,

I upped my dose from 50mg to 75mg last week and it gave me increased anxiety and panic attacks. As the week went on I felt the tablets stopping them and reducing them until this weekend I felt pretty good.
Sunday morning I was cutting up my tablets and the 25mg one was lager on one side so I probely took about 85mg instead of 75mg.

Later that night I felt shaky and anxious and had trouble sleeping. Then I had panic attacks through the night and this morning. Having trouble not obsessing about it.
Could this be because of extra meds or am I having a blip :(
