of course you will be hurt by a rejection, that’s pretty natural. I just went through the whole job process and got probably 15 rejections and all of them I figured if they didn’t want me then
1. They’re missing out
2. I wouldn’t want to work for a company that doesn’t recognize what I’m worth anyways.
The fact that you even had the willingness to leave a bad work environment and make a change is an achievement in itself. keep going, the reality of job searches are that it takes a lot more rejections to get a few acceptances. Be proud of yourself for where you’ve gotten to, and go into each job posting or whatever it might be with the attitude that the right employer will recognize what you’re worth and take you on.
Good luck
