Hi,
Much of what you said is familiar. I tried for a long time to deal with my anxiety without medication but it just didn't work. And even after taking several different meds, it is only recently that I found something that worked. BuSpar is a newer medication that is for anxiety, and it is working out really well for me. It takes several weeks to kick in, but it is the best that I've found. Also, the only side effect I have had is headache, and that is starting to taper off. I also take Effexor XR in conjunction with the BuSpar.
Taking medication, however, is not a cure-all. I have been putting a great deal of effort into changing the way that I think. For instance, I tend to feel enormous amounts of anxiety about events in the far future which will probably never happen and it is completely irrational to believe that they ever will happen. Instead of putting my energy into worrying about the future, I put my energy into reminding myself that RIGHT NOW, TODAY is all that I have. I focus on reality, and what is "true" right now. What are the facts? I try not to think about what the facts 'could' be, but what they are.
I am very aware that for a person who has GAD this is an extremely difficult task. But with the help of medication, it is working for me. It also helps to write out how I feel. Its one of the reasons why I wanted to join a forum.
GAD has been a contributing factor in the demise of more than one of my relationships. I have such a hard time trusting. But the man I that I am currently engaged to is wonderful. I have been able to explain to him the nature of my disorder, and he realizes that my 'distrust' and 'uneasiness' is not his fault. This is the first time that I have ever confided in a significant other about my disorder, and it has made all the difference. Therefore, I think that it is important for people who are in relationships to explain to their partner what and how they feel. You might be surprised at how understanding they can be. I hope this helps.
