How do we conquer these trust and communication issues ? Or are we just screwy.. ?

See the psychiatrist then - she is not your 'other' girlfriends, she is THIS one and if she has done nothing to break your trust then why not just choose to trust her (illness if for her to decide to share when she is ready) , it really is that simple. You CHOOSE to trust her. She is withdrawing from the relationship BECAUSE you are interrogating her - you will push her further and further away if you continue like this. What IF she is trustworthy, what IF she is the ONE that will not let you down and you make her push you away because she cant stand the 'cage'. Then you have lost the very thing you were trying to hold on to. Try grabbing a fist-full of sand and squeezing it tight and then try holding it with your palm open - are you getting my drift. If she didn't want to be with you then she will go - you having all her movements and conversations reported to you will simply make her go faster. If she offers information, for god sake don't jump down her throat about it - be cool - and she will keep offering information. If you get paranoid at what she tells you then she will clam up.
