hi kandersonn
i have a few suggestions for your friend. when stress creeps up on us and makes a real "anxiety" situation, then it's really a lot more difficult to resolve than just to say "don't let it get to you". below are my suggestions.
1) give all her problems and stress up to God. i don't know if you or she believes in God, but honestly this is what i do. what happens as a result is that overwhelmingly, things get better quickly. sometimes He takes my problems away or fixes them and sometimes He equips me to better deal with a problem that doesn't go away. Faith can do so much for someone who's hurting.
2) if God isn't an option for her, and i understand that everyone isn't all about Him and i'm not trying to push Him off on anyone...but...
what i would recommend that since she knows now she has a problem, 1/2 the battle has already been fought. what she needs to do is to uplift herself in positivism. some days are great and some are terrible, so you take the great days and love them. the terrible days...well you find some shred of goodness in them too and you push forward. time carries on and i'd tell your friend that if things are bad now, not to worry because nothing ever stays the same. this will change too.
i'd also tell her that her attitude will determine her success. if she tries to succeed and has a positive attitude about it, then 99% chance she will succeed. if she has a bad attitude and thinks she will fail, 99% chance she will fail.
so to put the whole thing kinda concisely...it's either all up to God or it's all up to her (your friend). let her know that no matter how she solves her problem, it's going to be up to either her or God. no person other than herself can do it for her. she has to pick herself up.
i understand how debilitating anxiety can be. when you gave me some more information about this, i feel like i understand a lot more about what to say that may help (i hope it helps). if your friend has a severe problem, then psychiatrists and drugs may have to be part of the solution. prior to going that route, however i'd try the other. that's just me
i hope it gets better for your friend. if you want to discuss this more, i'll be happy to discuss it further with you.
