You've diagnosed yourself well. Congratulations.

You have the answer, and you may even see it, but now what ?

Can you involve yourself in activities that would put you into contact
with other people ?

Are you employed ? Are you a student ? School and work offer certain
socializing opportunities assuming you are willing to be brave, to take
risks, etc.

You mentioned a time frame: one year. One year where you have been
having grave difficulties adjusting to a new scene. You have fallen into
a rut and I think now you are inflating the magnitude of your ills. Cut
your pain down with perspective. Be less subjective, less you-centered.

You may be really surprised what a little momentum can do for you if
you are able to take sensible risks, overcome any shyness, and
venture out to meet new people (in the flesh) within a safe, controlled
environment (school, work, through family, etc.)

also, I would suggest you share your problem. Talk to any and all
sympathetic family members or seek professional help. You must
be able to vent your frustrations. Don't let them percolate inside. Don't
let your anger or depression do your thinking.
