Dear Kelly: first of all, depending on your age and symptoms, heart disease needs to be excluded. Afterwards and once you have been evaluated by a psychiatrist or clinical psychologist and these feelings found to indeed be related to panic attacks and anxiety, I would then tun to meditation and/or cognitive behavior therapy to deal with these symptoms. Be cautious with use of lorazepam/ativan as it can be habit-forming and people might even feel worse once the medication wears off. Good Luck!
You can google something like "scholarly articles treatment panic attacks," and what will come up are studies showing that a combination of medications PLUS cognitive behavioral therapy is the most effective approach.
If for some reason you are violently opposed to medication for what is in fact a medical problem, then probably you would still be able to fnd a therapist who would be willing to try you on cognitive therapy alone.
