Angelina,
What you are feeling is NORMAL. I had a very hard time too. I work in customer service so I can understand the talking at work problem also. I wish I could give you a hug....you will get through this. You will come to terms with this in your own way, at your own pace and that is ok. I'm sorry the people you work with are not sensitive to what you are going through but people can be rude. Do you have anyone at work that you are close to? I used to walk with my boss every day and she was a huge help to me and still is.
I would like to thank you for what you do. My younger sister is in special education classes and what you do is a wonderful thing.
Please feel free to send me a PM whenever you need to vent. I hope this site is helping you also...there are a lot of wonderful people here.
