Should I hire a lawyer or Contact EEOC?

I reported a coworker for going into my computer by creating a file with his name and my id number. I went to HR and Supervisor and have since then this person access my work daily. My work has been changed causing me not to be to do my work. Today someone went into my lock file cabinet and stole something. I complained again but I see Management just want me gone. I am so upset I don't know what else to do. I reached out to Corporate and are supposed to be investigating but I don't believe it since the harassment and retaliation continues each and every day. I tried not to use the race card but each time I speak with management or HR my issues are sweep under the rug. I have four coworker that are sabotaging my work I can't concentrate because I feel I will be let go any day now.
