Anxiety/panic disorder is taking over my life.

I've recently been diagnosed with anxiety/panic disorder. My main symptom is extreme lightheadedness. Usually I start to feel dizzy, then feel a panic that I might pass out. It happens at random times and I can't bring my self out of it when it starts to happen. Today, I was having lunch with my best friend and ended up leaving without eating and telling her I had an upset stomach. This is starting to take over my life! I've been to my doctor and she suggested a daily preventative medicine like zoloft. However, we're still TTC and after 2 miscarriages, I'm not interested in a medication that builds in my system. She gave me Alazopram to help the symptoms as needed but I've only taken a half of one. I wish I could fix this on my own. But it's so scary and I feel crazy and helpless! :( It's also happened random times in the car, while washing dishes, etc. Can anyone share any experiences or advice to help me reverse this issue? I can't keep letting it control me. I'm a teacher and I need to feel like my peppy self when school starts back! Thank you to anyone who took the time to read this!
