I was told by my therapist that some of my behavior sounds like OCD so I was diagnosed with it ,but I mainly suffer from GAD. I wanted to ask if these sound like OCD or anxiety?

• Overwhelming fear of being poisoned by chemicals or getting deathly ill from germs- thus I excessively wash my hands. Especially after I clean. I do not like chemicals but I must clean at work. I also have a fear that I will develop a disease or that taking multiple medications will harm or kill me.
• I need to be answered right away with emails, texts, phone calls. Overwhelming impatience leads to excessively checking my emails, phone etc. Also I am a college student and no matter if my schedule is right as it should be I am so indecisive and just feel the need to search through the classes and keep changing it until it feels just right.
• I get worried that I always do something wrong or that people are talking about me or do not like me. I cannot stop thinking about past events that I was embarrassed by my behavior in front of people. I obsess about it so much. I cannot shake the memories.

I was wondering if these are a mix of OCD and anxiety?
