Anxiety and depression when trying to concieve

I've dealt with anxiety, panic attacks, and depression for as long as I can remember. I decided to get off the meds while trying to concieve a child. The result has been terrible. My panic attacks dictate my entire day and I cry constantly. I feel like I've lost all control and the stress im experiencing is hurting my chances of successfully conceiving. I also recently started a high stress job and I think im going to quit and just tell my husband they let me go. I'm afraid it's going to drive me to a breaking point if I don't bail but I feel like a total failure. If anyone can relate to my situation I'd greatly appreciate some insight/advice.
