How do you ever stop taking meds?

I had my first full blown panic attack last Wednesday, and was given a small script of Lorazepam for short term use Thursday, the day after. Seeing as it's been four days, and I've been doing better, having only taken half of .5mg at a time yesterday, I thought I'd try going without any meds tonight. I'd read some good literature on handling panic attacks, accepting them for what they are, breathing exercises, and such, and felt like it was time to give it a go. I took .25mg at noon, got a good run in late in the afternoon, had a healthy meal, and was doing fine as of 10PM without taking anything, then BOOM! Heart pains (heart problems weren't even part of my first panic attack), lump in the throat, awful feeling that something bad was happening. I tried talking myself out of it, I tried accepting it, I tried just laying down, I tried breathing exercises, and nothing could stop it. I ended up taking .5mg and feeling better fifteen minutes later ...

I knew what it was while it was happening, and couldn't do a darn thing, and again had to resort to taking meds. So my question is, how do you ever break the cycle? How do you ever stop relying on taking meds once you've started? I feel like I've already read enough in the past four days to understand that nothing bad will come from these darn things, but when they hit I'm helpless, and I have a hard time seeing how some therapist (haven't had my first appointment yet) is ever going to be able to do anything to lessen these, or how mindfulness (I'm getting into it) will ever help me in the midst of panic.

Had a good day, took five minutes to ruin it all. Thought I had made progress, but I'm realizing I made none. A week ago I had never had a full blown panic attack, and now I'm already stuck in this cycle. Something's gotta give?

It's funny, I do have to remind myself it's been less than a week. And upon re-reading my post I'd have to say my suggestion that I don't have faith in therapy that I haven't been to, because some literature I read online failed to quell this panic attack, is a bit overkill. It just felt like a huge let down when I thought, four days in, I was ready to handle this, and I fell back into that helpless hole.

So much for, "accept that the attack is happening and embrace it". That advise, from another website, didn't go over too well, haha.

Anyway, thanks for replying. Engaging in some conversation with somebody who understands what I'm going through is of much help. I think I'll stick to at least the half of .5mg a couple times a day for now.
