Thank you, AsToldByYaya...I still struggle at times with self-esteem but it's mostly if I feel that I have I fell short in satisfying MY standards for myself, not someone else's. I used to feel pressured to fit in and be the "IT" girl, both in my high school years and my military years as I was younger and did not understand what it meant to be an individual.

Hi Madisonjayde99, it's really hard to suffer with PCOS because it makes things really hard in terms of being confident. Ironically, I believe I hold my head up higher since I've gained weight, grew extra hair on my chin and endured darkened patchy skin with PCOS! Simply because everything that I've been through including PCOS has made me who I am today, a much stronger person of whom I am proud to be...Remember that everyone has a story, secrets and insecurities despite whether they let it be known or not. Nobody is any better than you! At any time ANYONE can look stupid, ugly, poor, useless etc. because we all see each other differently. Don't worry how others see you to validate how you should feel about yourself.

I've been reading positive affirmations daily to help with my confidence. There are apps that can help or I made a flip book I keep in my purse.

Wow this was an amazing anwser and extremely helpful. I aspire to have this level of confidence everyday. As you stated all struggles have made us into who we are

Self-confidence is a life-long thing, not something you can fix overnight. Things that have helped me:
1) Think about the things you love to do, pick one that's especially useful and become an expert in it. Make it something really specific so you can be a real expert without spending a decade learning it. Then enjoy when people come to you asking about it.
2) Do something hard, something you aren't sure how to do. You may get to choose it, or a situation may force itself into your life. Get support however you can along the way, but keep doing whatever needs doing. Keep taking each little step that you think might lead you forward and then see how tiny things turn into big steps forward. Knowing you can find your way though whatever life throws at you gives a person hope and self-confidence.
3) Affirmations can work, but they feel so silly at first. There's power in saying the things you want to believe aloud, even in a whisper. I was recently in an accident, totaled my car, and I swear affirmations help me be less jumpy when crappy weather starts to trigger me. I say aloud to myself, "I am safe" or "I drive a safe car". I don't believe it yet, and I feel dumb talking to myself, but I swear it helps.
To create an affirmation, think about what you admire in others but don't see in yourself, maybe what you wish you could do. Think about a simple and positive phrase that someone who loves you and trusts in your abilities might tell you on that subject, like maybe, "I fix my own problems" or "I am a good friend" or "I keep trying no matter what" or "Even when I'm scared I do what I think is right" or...I just can't guess what you might need to believe about yourself, but think about the crux of what you don't like about yourself, and then have someone you trust help you phrase very simply what you wish you could believe. Practice saying the phrase to yourself a few times a day. A friend's mom forced herself to say, "Hey good lookin" every time she passed a mirror for years. It got easier over time and eventually she didn't need to say it any more.
4) Notice really smart people doing really dumb things. Notice that you only do some dumb things and that they usually don't hurt anyone. Feel better!! And laugh at all the silly stuff you and everyone else does/says all the time. I promise you're judging yourself more harshly than anyone else does. They're too caught up in their own silly drama to even notice most of the time. Try to be a better friend to yourself. You wouldn't let anyone talk to you the way you're thinking. Try new stuff that interests you and find people who bring out lovely aspects of your personality and your talents/skills, then find ways to spend more time with them.
