Are these intrusive thoughts, anxiety, or should I be concerned?

Okay, so here it goes. In January 2009 I had my first panic attack and had anxiety that lasted a week, after that something clicked in my brain and I was fine....a few weeks later I found out I was pregnant. Fast forward- when my son was 9mths old (July 2010) I think I had a little breakdown. I stayed so stressed out from school, being a mom, helping my boyfriend build our house that I started getting headaches and staying anxious. July 10 I had a migrane and had what the doc described as a aura. Ever since then mentally I have not been the same. Since then, I was TERRIFIED (to say the least) that I would have a brain aneurysm and die. This consumed my every thought! This lasted several months and then I started feeling like I had something wrong with my heart and to this day I still have heart palpitations, check my pulse 10 + times a day, etc. I chalked it up to anxiety.

I have no insurance to go to the doctor so I have not been on any anxiety meds or anything and until the past couple weeks was on what I like to think of as the road to recovery. I could sleep, relax just a little. Then I started having this tingling in between my eyebrows and on my nose sometimes.Not numbeness just tingling. Then those thoughts start creeping back up....I'm going to have a brain aneursym. I had convinced myself that I was too young to have one and then a girl I went to school was diagnosed as having one. She's 23and wen tothe doc because her face went numb....I don't know if subconsciously I started to thinkabout this or what. Then yesterday I went to work and my boss was talking about her nephew having one and his symptoms and it totally freaked out and left the room. I can't get it off my mind. Then I get on this community with others that suffer from anxiety and the first post is about a woman who fears the same thing because her mom had one 12 yrs ago. That did it....I am now terrified all over again. They were talking about seeing floater...little spots (which I have always saw) being a sign and now I am terrified. Please tell me I'm just panicking! Thanks
