Hi Movesin,
I too suffer from anxiety and I can totally relate to some of the things you are going through. I am sorry you don't have any support at home. This must be difficult. What helps me when anxiety strikes me, is to take one step back and to prioritize things in my life. You said that you need to make many decisions now. Start with one that you feel is the most important one, the one that will affect your life the most and work towards resolving it. One decision at the time. I hope this helps a bit.
