A couple of quick, but I think important things...
So good that you came here. Lots of smart people here who can truly empathize with what you are going through.
****I'm sure you aleady know this, but it is worth repeating, if you have suicidal thoughts, it is best to get yourself to am emergency room immediately, right away, ASAP! This is nothing to be ashamed of. Just, simply do it. Protect yourself. This is urgent.
Also, are you seeing your physician (MD) regularly? This is vital! He or she should know right away that you are concerned that your meds aren't working as well as they should.
In addition, are you seeing someone for talk therapy? (Also vital!) Sometimes (not always...but sometimes) a psychologist or some one else in the mental health field might actually be a little better for 'talk therapy' than an MD psychiatrist who usually has more expertise with medications.
Prozac is sometimes a tricky med with bipolar illness and you might want to ask the doc about it.
Don't hesitate to get in to see the doctor again or even to get a second opinion. Make sure you try your best using healthy means to get the proper sleep at night and then have something productive to do each day. Even if for now it seems like something smalll...that is fine.
Don't worry about any mistakes. That is the past. Tomorrow is another day.
Listen to those here who understand and are pushing forward even having to contend with this difficult illness. Let your doctors and those with experience help you. PLEASE let you doctor know right away what is going on. And as best as you can, take whatever steps you can to help yourself to be healthy, happy and moving forward. It starts with calling the doctor and telling him immediately exactly what is going on or going to the ER as stated above.
Sending good thoughts.
