Reaction to Albuterol -- sore lungs , tachycardia , fatigue

I'm a 33 yo male, and have had asthma since childhood and have always taken Albuterol. Recently, however, it seems that I can not tolerate it at all. In the past 3 weeks or so, every time I take it (either MDI or nebulizer), my heart races and pounds, I feel VERY much out of breath (like my body can't regulate my breathing pattern), my lungs become very sore, and sometime I even feel more tight-chested than before I took it. I also get extreme fatigue -- climbing up stairs, laughing, or emotional stress of any kind tires me out. The effect wears off after 4-5 hours. I now avoid taking this previously life-saving medicine and have no idea what to do.

I'm perfectly willing to admit that it may be anxiety-related, but the physical symptoms are far too profound. Can people become resistant to Albuterol? Are my lungs too inflamed to use this?
