Is it just me?

Is it me or does everyone feel like you are fighting a losing battle? I cry for help from Jesus everyday and I feel like so much more junk is laid upon me. I keep holding to the promise that He never gives you more than you can handle, but, sometimes I feel like I can't handle the pressure. I am not even close to being perfect and I guess I have low self-esteem. Do you feel like your worthless? Even though I feel these painful thoughts, I will never surrender my love for Christ. He is the one true and almighty god!
