time for work

I seriously dread going to work every day. Like its very hard for me to go. I get anxiety about it. Once I have a job, I'm never satisfied even though I should be. I know I should feel blessed to have a job, even if it's only part time. But I want an even better job sometimes with better hours, etc. however I am scared to work a full time job because its such an issue for me to even wanna work part time. I don't think it's cuz I'm lazy, I think it's anxiety. Does anyone else go through this???
