Proofread your resume yourself and get someone else to do it. Make sure you submit cover letters. Don't use different fonts/styles. If you have no experience then some volunteer experience could help though I'm not sure how good this advice is since it would take a while to set up a volunteer position.
I'm sorry to hear that OP and I'm really sorry that you have to put up with some of these shitty comments. But at this point, it is best for you to start searching externally. Ask friends, family, etc. Don't worry, you'll find your job :)
