I can relate. I have the same problems with obsessively worrying about anything and everything. I'm constantly worrying that something i say to someone will cause them to not want to be friends anymore. It gets to the point that I don't want to take a risk by being open, and I have become a very private person, overly private a lot of people say. It's very painful to feel this way, constantly worrying about losing the people who matter too me. You're not alone here. We understand.
((((hugs))))

I too can totally relate. I also pick up on the tiniest, most 'insignificant' things, such as a line in a movie, a news story/article, a health concern, a fleeting comment etc, and spend waaay too much time analysing and replaying it in my head, eventually creating an alternate reality for myself in which this "thing" seems to have a much deeper meaning that it actually does, and I convince myself that it must tell me something dark and horrible about my "real self". As a child I would lay in bed for hours each night worrying about particular things - and I would worry about the SAME thing for months or even years. As I've gotten older my sleeping habits have improved but I still have nightmares related to my phobias and the things that I'm worrying about during the day.
The thing that caught me about your post is that you're worried about letting your worrying interfere with your relationship. I too have found the love of my life, and only over the past few months when my anxiety levels have been heightened has he come to realise the true extent of my worrying and anxious thought patterns. I feel so guilty for burdening him with my issues, and I worry more than anything that my anxiety will come between us... but at the end of the day he loves me deeply and only wants to help and support me through all this. I hope that you have the strength and courage to be open with your partner and to discuss what's going on, as I'm sure you would find a lot of love and support from them.

HI, there, you sound a lot like me, so I want to extend my empathy to you. I would like to share with you, though, that I have spent the last year with my therapist who has been a tremendous help to me in getting over my ptsd symptoms. THAT, in turn, has made a huge difference in the extent of anxiety that I feel today, In other words, after I dealt with my "scarey" issues, the things that internally upset me the most, the anxiety level has gone way down. Also, my pdoc has prescribed and I do take anti-anxiety med. during the day to help as well. I'm telling you this as a suggestion to you, in the hopes that something will help you feel better and give you peace of mind. I wish you all the best!

I am a constant "worrier".
After I finish worry about one thing, I"ll worry about it again after some time. ...while I'm writing this, the eHarmony (an online dating site) advertisement pops up...I wonder if I could find someone who would be willing to listen to my worries and understand them. It's relieving to know that I'm not alone, thanks for sharing your experiences. You guys have given me hope.
