Hang in there Sapphire...it is early days. It is a big transition, a new routine to slip into and also activities that are new to you. This is only another stepping stone. You will return home, hopefully with a solid mental health plan in place to help you deal with a troubled mind.
I understand that temporary separation from your dog must be difficult for both of you. There's nothing quite like wordless K9 understanding and unconditional acceptance of who/what their humans are. A joyful reunion to look forward to when you are ready.
As Neil pointed out, each and everyone of us is unique and so can make a unique contribution. The combination of your past experiences, good and bad, and your reaction to them means there is and never can be anyone quite like you.
I agree that being around people is not always easy when we have been isolated (either by choice or by Life). Shunning contact only reinforces self-effacing tendencies (and confirm the false belief that we may be hopeless and unlovable). Due to abuse in childhood I felt for years that letting people get close meant I would get hurt. Until I realized that -as an adult- I had a voice and could use it to take care of myself. I was no longer helpless.
Well done for being proactive and giving it your best shot in spite of the difficulties. A good reason to be proud of yourself.
