Samantha,
Hello! I can empathize with you and most of us here can. I also have a son and started having panic attacks when I was 21 yrs. old (i am now 23). I worried that I wasn't going to be there for my son and I felt guilty that I didn't want to leave the house because he wasn't going to get to experience things that kids should get to experience. What I found to be helpful is breathing exercises (helps with dizziness, shortness of breath, and derealization), eating healthy, taking a multi-vitamin, getting adequate sleep at night (this one is a must because anxiety gets 10x's worse with lack of sleep), and getting some form of exercise. It is also good to try to get your mind off of the anxiety and the physical sensations that come with it because the more you let them consume you, the worse they will get. Communication is also a must - talk with your fiance, mother, psychologist, whoever so you have someone who knows what you are going through and can help you through it. You also need to address your sources of stress as well because you are probably having the panic and anxiety from your upcoming wedding, mother,etc. so you need to find a more productive way to deal with it all. I hope this helps you in some way and just try to not let the anxiety take over. You need to keep yourself out there and continue to do things because the longer you avoid situations the harder it is to get better. I was really bad for about 9 to 10 months and am finally getting better with the help of this site, the program, and a psychologist. Be strong, be optimistic that things will get better, and keep us posted.
