Severe Anxiety/Post Partum Depression! Boyfriend doesn't understand! HELP PLZ!?

I had a baby in January. I was getting worried because my ex was coming around asking about my 3 yr. old. I talked to the doc about anxiety, she put me on 50 mg. zoloft. Within a month, my boyfriend and I were arguing more, I got jealous easy, anxiety wasnt helped and I became depressed. Doc put me on 100 mg. I have had panic attacks 3 times a week and get angry so easily/fighting with boyfriend all the time (never fought before this) He things meds are making me more crazy. I agree to an extent. I called doc again in hysterical in desperation after another attack. She told me 150mg. of zoloft. I said no, i dont want to take it anymore. She said Wellbutrin. I said the only thing I want to try is BusPar, (I read its good for anxiety and non-addicting)...Although actually I really dont want to take a pill everyday, I feel like I cry all the time because I cant control my anxiety, its a vicious cycle. I beg my boyfriend to understand, he in turn blows up at me!? What I really want is to get off all meds and just something like a valium or xanax for the time being until it dissipates. My doc wont do it. Why do I have to feel guilty to get treated for this when I clearly need it. I havent tried the buspar yet but I cannot bear to take something else that is going to make it worse. My relationship is in crumbles. I need advice please
