Are these symtoms of anxiety?

I don't know if these are symtoms of anxiety attacks because I don't feel like I am going to die but I could be sitting watching TV and I will start crying for absolutley no reason! my heart feels like it is fluttering and I feel like I have a lump the size of a baseball in my throat. I feel like I have to take deep breaths constantly. The main problem is it's throwing my sleep schedule off i wake up at 2 a.m everynight even if i take a tylenol PM. Is this just something that will pass? I feel that If I explain all of this to a doctor he will just look at me like I was crazy!

I had a very similar experience with anxiety. I work nights and was having trouble sleeping during the day. and on weekends when I switch back to the day routine, I would wake up around 4 am and when the sun came up I would be ready to sleep all day.
When I noticed the anxiety was when I started waking up with a worried feeling all the time and it seemed like my stomach was in knots but I could not explain what was bothering me. Then there were times the littlest things that happened would send me into a panic feeling.
I went online and found out tha St.Johns Wort help treat anxiety and depression. I went to wal mart and tried it and it has worked really well for me. I take 2 capsules 3 times a day. I am much more relaxed now when I go to bed and I sleep much better and the worry and stress is more managable now. its worth a try.
