I just feel like I am worthless all the time
You’re not worthless. I dont know much about your details but I just want to encourage you to find your purpose, because I know you have one. We all do.
You are not worthless my friend. But I can relate to that feeling as I fight it very often, myself. I hope that you are able to find strength and courage to push through these feelings and that you find a sense of fulfillment in life.
You’re not worthless. You have valued and meaningful to me! In purpose seek your hobbies, job, whatever you value and go for it like @Benaiah said. Also in that make sure to smell the roses along the way. You are doing something good, you just don’t recognize it yet. I believe in you friend.
