Hi @gymgirl240
Firstly, it is natural to be feeling the way you are after a traumatic incident as you have experienced. Secondly, it is also natural for you to be uncomfortable around other people right now also.
Try not to be so hard on yourself - no-one that has not experienced such a trauma can fully understand the massive impact it has on you. It is one of those 'subjects' that is often hard to talk about and just as hard to hear - most people do not know how to react or act when someone discloses a SA to them.
I would suggest you contact your local Sexual Assault Support Service for some help. They can provide you with support both now and through any legal proceedings (if this happens). It is also a great place to connect with other people who have experienced similar things.
Often it is knowing that you have been heard that begins the process of working through this @gymgirl240 - and here you will definitely be heard 
There are many here who will listen and I suggest you familiarise yourself with the Community Guidelines - which can be found here - so you are aware of what you can and cannot post - especially re: content and safety.
Lastly I want to let you know how courageous and strong you are - not just for reporting your boss but for seeking support here on the forum
Many have walked the same path as you are now but not all have had the courage to do what you have done - and that is massive. Keep talking, keep reaching out and keep accepting all the support that you are offered.
You are not alone...
