Hello and a warm welcome to HealingWell and the A & P Forum. You are not alone as this is where you will find many members with the same issues as you have described. I am Kitt.
It feels to me like you may be experiencing anticipatory anxiety. Anticipatory anxiety is where a person experiences increased levels of anxiety by thinking about an event or situation in the future. The worries you experience specifically focus on what you think might happen, often with catastrophic predictions about the event.
I know how hard it must be for you to have moved so far from home and I am thinking that perhaps this has triggered your anxiety to escalate. I know it is very hard to do but try to kick the "stinkin thinkin" thoughts to the curb and do not let the anxiety rule.
Call your parents and family back home and just touch base with them as often as you need to. Also looking for a therapist is a wonderful idea. I think you know yourself very well and you sound very wise and well grounded.
Coming here and talking to us is another way to help reduce your anxiety. Just post what is on your mind and know we are here to support and care for you.
May you walk in peace,
