I'm so sorry to hear you are hurting so, and even lacking the support that you do, in fact, need desperately. If I were in your shoes, my first course of action would be to phone my primary care physician and explain the situation. I am not familiar with Crohn's, but it does seem that your doctor could at least get you started on an anti-depressant medication to take off the edge; this will also help you achieve the goals that you will be reaching for when you do get in to see the therapist.
Medication is a very helpful tool in conjunction with the therapy; and, of course, you have a lot of work to do for yourself and some self-help will prove beneficial. The medication will help you find the strength you need to get the most out of the therapy.
Before you go to therapy, write down what is bothering you and what your goals are. That way, you will not waste unnecessary time and/or monies solely on talk therapy that only provides relief during that hour you are in there .... you will need applications for daily living. There is also a lot of helpful information in the Panic-Anxiety forum; many of the folks in there have been through the same, and have some very good information posted that has proven helpful.
The therapist can also be very helpful in gaining the understanding from family that you not only need, but also deserve so that you can have an effective recovery and/or relief without such an extended timeline to reach that better place. It is very difficult when support is lacking and you feel so isolated and alone; been there, and so sorry to hear that you are now.
(((Hugs))) and many prayers for you and your family.
P.S. Meanwhile, try to pamper yourself and look into some relaxation therapies and techniques that are individually suitable for you. Also bear in mind that it can take up to six weeks for the various anti-depressant meds to kick in to full capacity. However, in some cases it is only a matter of days; I'll keep my fingers crossed for you. My only remaining suggestion is to try hard to relax and be patient until help arrives from the doctor and/or therapist.
