There are many different kinds of anxiety medication. What kinds of have you tried? There may be classes of medication you have not tried that do not cause tiredness. It sounds like it is time to visit the doctor to take another look at it. If medication is not an option then you are going to need to take other steps - therapy, meditation, breathing, learning to change your thought patterns, etc.

I understand being dealt a totally crappy and overwhelming hand. Unfortunately sometimes that has to happen. Yes, you may need to spend some time feeling bad about it, but getting stuck in that place will do you no good. It only makes you more unable to do what it takes to make the situation more manageable.
