Lexapro back to Paxil.... Question?

Ok, so my attempt to switch from Paxil to Lexapro has failed miserably.  Today I started back the Paxil CR 12.5mg with Lexapro 10mg to eventually get back to where I was at when all of this anxiety started.  Rewind 2 months and I was on Paxil CR 25mg & Clonazepam 1mg which I take both at night.  I felt a bit more anxious and I thought that the medicine was pooping out on me and I decided to try Lexapro.  Well, the old body hasn't responded to the Lexapro after 8 1/2 weeks and the 2 week withdrawal from Paxil CR 25mg didn't help things.  

My question is, when people talk about a drug "pooping" out on them, what does that exactly mean?  Is the normal dose they are taking not effective anymore?  Have they went to a higher dose and still not had success?  I just wish I would have went up to Paxil 37.5 instead of throwing in the towel on another med and dealing with the Paxil withdrawal which the doctor said wouldn't happen in the first place since they are both in the same SSRI class.  Yeah right.  Well I am done with my regular doctor now and have lined up an appointment with a Psychiatrist to help with my medication.  There has to be a light at the ned of the tunnel.  I'm a father of 2 little ones with a supportive wife that is having a tough time right now because my issues interfere with everything.
