Hey Kitty099
I have tended to suffer anxiety problems and mild depression for as long as i have ever known, however i would say there have been times 1999/2000, 2002/2003, 2005, 2007 and this last year or so where the depression fluctuates to a more severe form and there are also especially more recently a strong tendency towards paranoia about certain things which causes me to rule out certain life choices out of some sorta misaligned sense of reality.
I would also say that bullying problems, relationship problems, and some dubious friendships have aided in chipping at my self esteem and self confidence in recent times too.......its tough, yeah you try CBT and its pop up book psychology, u try meds and its side affect city with meager if any positive results.
the best thing i can only imagine you can do is try to build some friendships and work on building trust with new people, maybe look to see who you could find to build up a relationship with, try and get a room mate and a part time job while you do whatever studying your doing etc........ it will never go away but you can try and build towards ways to keep it in check.
i myself am stuck right now at the end of the line when it comes to several friendships that have lapsed and suffered an irreconcilable difference, a couple of relationships gone bad including a one where i was engaged and having finished my Masters Degree still living at my folks place and trying to figure out my next life move in terms of career or just becoming basically independent.
it is tough but you can get positive and in control of it, but it will always be a struggle.
