I know about FEAR. I know about ANXIETY. I am not so certain of the differences.
I did a little research and found a helpful "fact sheet" from the Mental Health Association.
Fear and Anxiety have similar emotional symptoms. With a fear, we generally know what it is that causes our symptoms; i.e., we know what we are afraid of. Healthy fear protects us from doing unsafe things or getting ourselves into potentially dangerous situations.
With Anxiety, the reasons for our emotional symptoms are not clear to us; we don't know WHY we feel a certain way, and that "unknowing," that "lack of control" can send us spiraling off into a serious "panic attack," a chest-tightening, heart-palpitating, sweating, nauseous experience that can get worse and worse over time, even becoming life-threatening.
When our normal little "anxieties" about life begin to affect our ability to function in a "normal" way, we are said to have an "anxiety disorder."
There are several identified anxiety disorders, among them are Obsessive Compulsive, Post-traumatic Stress, Agoraphobia, and many other phobias. All of these conditions merit professional assessment. There are several avenues for treatment including counseling, medication, and alternative therapies.
I know individuals who have lived with uncontrolled anxiety for DECADES! Some just thought it was normal; others knew they were "different" but thought it was just something they had to "deal with." When properly diagnosed and treated, these individuals experienced amazing improvement in the quality of their lives. More than once, I heard: "Oh, if I had only known this before!" What a shame--to have spent 30 or 40 years of their lives in fear and isolation.
Don't believe that there is nothing that can be done. Talk to your doctor; get a referral and have a professional evaluation. You might be denying yourself the wonderful life you deserve.
