not to be indelicate but are you on meds of any sort? Anti-depressants, anti-anxiety, anything? If not, do you have insurance? If you do GO to psychiatric NP or DR and tell them your husband is screwing around with your lives/marriage/future and you need the best pharmaceutical support to help you think clearly and make the best decisions. They will also help you rest better, which will improve your acuity.
I would NOT suggest going to your family DR only because they cannot be specialists in DRUGS and what works best for what or in conjunction with other meds. You might ASK your family doc to recommend someone but don't trust your GP to prescribe the first time around. Besides if you go see someone it will be taking ACTION and make you feel better. Sometimes that in itself is a reason to go.
