Anxiety is ROUGH as we all know. And to people who don't have it, they can never understand the struggles we go through.
Regarding the Paxil: Give it a shot. I felt the same way you do, but I was so tired of feeling like I was going to crawl out of my skin all the time. So, I stared it and am I EVER glad I did. Remember, you also need to make changes to your lifestyle. You must find things that make you feel good naturally. Exercise is HUGE I can't stress that enough. Reading some motivational books really helped me. Find simple things that make you relax and quiet your mind. It's all very worth it AND it makes you healthier not only physically, but mentally & emotionally. Why? Because you build your self esteem when you respect yourself enough to take care of yourself.
For me, anxiety has been a blessing in diguise. I absolutely HATE IT, but it has taught me how I need to live my life and to bring kindness & compassion back into it. Not that I wasn't kind & compassionate, but I needed to remind myself to use it more. I smile and say thank you ALWAYS, I strike conversations up with strangers just to bring a smile to their face, I always say "bless you" when someone sneezes, etc... it's the little things that will turn your life around. Trust me on this.
The Paxil dosage they told you to take is what you should do. Then gradually go up. I would say in a month you'll be feeling a huge difference, perhaps sooner. Also incorparate the other things I told you about & start using them. I promise you, you CAN and WILL get better if you do the things your body is begging of you. We are the only ones who can truly love ourselves. WHen we worry and don't take care of ourselves, that's not respecting who & what we are.
Anxiety doesn't define who we are, the way we treat ourselves & others does. Believe in yourself and SMILE everyday.
