No, but its admirable that you are looking.  Look in phone book or online here..for NAMI  National Alliance for Mental Illness...follow links and you probably will be directed to a local NAMI affiliate.   If there is not one isn BUcks county, there is a very active one, I understand in Montgomery county, there is one in Berks County, and a very active Main Line NAMI.   THEY do have support groups.   BUT....he may need more and if he is feeling suicidal, you need to maybe call 911 or drive him to the emergency room.   If he can make it, call a reputable psychiatrist (if he isn't already seeing one) and tell the truth about how bad it is.  If he has a good doc already, I think he/she will either get him in to the office immediately to assess need for hospitalization (which can really help even if for just a few days....its ok to go...even if he is reluctant...its ok and more, its necessary for his pain.)  You are a good advocate.   Don't let the hospital emergency room, if thats where you end up....treat this any different than they would another emergency.   Sometimes you have to answer the questions a bout suicidal with "yes, a plan"....you will figure this out.. but PLAN seems to be key work in admission, whether in fact a plan has beed made.   I hope your husband gets the help  he needs.  I just realized I only could see the first three lines...so this may all be things you already know. 

please pardon all those typos and missed words, etc.   I type so fast in a hurry because you are both suffering terribly....I have been the family member in your shoes.   

A family member of mine was given Risperdal recently for depression.  It is usually used as an antipsychotic, but apparently a very large study on its use for severe and persistent depression has been completed, with good results.   My family member experienced good results, rather quickly, for depression...with this medicine.  It has its downside, but I read somewhere (I think) that if person is admitted to er, sometimes they will use this ( I guess if psychotic, but you could be the educated person who asks the doc about it at least) to get almost immediate relief  ....then not necessarily use it for long, but stabilize (put the person out of their pain) until plans are made for next move.  If the er doc doesn't know about the research...or current doc doesn't...ask, if he doesn't go to er.   I think they treat the really bad psychotic episodes with this med injection....to quickly settle things down... just a thought.   Good luck.  My family member was so relieved (though never psychotic, thankfully) from the bad feelings (especially any aggressive ones), that he pleaded for me to try it..  I have been on some medications for more mild depression/anxiety - possibly bp, but I don't like to label.   I think I'm doing ok, but his answer is you just don't know you have been feeling bad for so long.  I finally asked for smallest dose to try.  Doc said smallest dose is the "granny" dose....so I said...I'll take that.   But haven't taken it yet.  I'm kind of anxious to try it....I also had much success with Lamictal.  MUCH.
