I'm feeling the same way as you right now. Don't think of that feeling as a reflection of who you are as a person; think of it as your mental health that's stopping you from being who you really are or who you really want to be. In your situation (and mine) it's best to know there's people out there in the same situation as you, to keep a positive mindset, and to know that things will get better. Keep pushing on day by day and slowly reach out of your comfort zone. Good luck.
