Cyd,
When you meet the right person, the fears you now have will be exciting to overcome. The thoughts you have now only fuels that fear but you have to see them as irrational and not practical because in the present moment, you don’t have a partner to work on these things with. See this experience as an opportunity to better yourself. The better you are, the better you can care for your partner. It’ll be easier to overcome your fear when you have someone worth overcoming them for and you too will benefit from this. It will make the experience with them even more beautiful.

Expose yourself in a safe way to your anxieties about this and slowly begin overcoming them one step at a time. You seem like a good person and if you push yourself to commit to working on bettering yourself, you will undoubtedly find success. Go slow, know what the real issue is, and take steps to correct them.

Remember that you’re not being held at gunpoint to feel the way you do. It’s a choice. Commit your thoughts to thinking more positive about this, see yourself overcoming these obstacles, even if you don’t feel worthy, always know that you are.
