I am Type II Bi-Polar and Inattentive Type ADHD and have had my ups and down with medications. Though you're feeling like a zombie, listen to your doctor's advice. If the Klonopin is making you dizzy, etc., you need to let your doctor know that and maybe they can prescribe something else to ease the transition.
I've been up and down with meds and yes, it stinks! I started off taking Zoloft, then was on Lexapro for 1-2 years until I experienced HORRIBLE side effects (joint pain, fatigue, and I was developing an ulcer which landed me in the ER!), then Prozac which worked well, yet I was still constantly tired. I then was formally diagnosed in 2005 and have been taking Adderall since (for the ADHD). It's been tough finding a anti-depressant since Depakote pushes me too far into the Depression, I'm allergic to Lemectil, and Wellbutrin was again making me too tired, basically cancelling out the Adderall.
I've also been there where I feel like a raving lunatic! Many times I've caught myself getting too angry, snapping at someone and had to step back, take a deep breath and count to 10. When I get too agitated I take a walk, do something relaxing. I also have a great support system so if there are days where I'm feeling totally out of it/raging beast I can have my son go visit my parents or he does something special with my ex-husband. My son also knows about my "illness" and knows there may be days Mommy is tired, edgy, etc and not to be scared or think it's his fault.
Most importantly, talk to your doctor! Let him/her know what you're feeling and see if there's a different med to prescribe to you. I saw the comment about meditation and it's actually something my therapist recommended to me.
