Hi D (searchingforpeace)
I haven't read all of the responses to your post, but I did want to respond to you if you don't mind my doing that without reading through the entire thread. I'm not feeling very well myself tonight and so reading through the whole thread is a bit much for me, but I will come back and do that tomorrow.
Firstly, I just want to say...
Wow! You really are suffering dear. I see it in your words and I feel for you, so much. I can just feel the pain dripping from your words as I read them. I'm so sorry that your hurting. I just want to take your hand and tell you how precious you are to our Heavenly Father, D. I know my words are just another stranger, telling you how much you are loved by your Creator. Yet, I need to tell you anyway.
I can see that you do understand that G-d loves you and that you being bipolar does not keep Him from loving you. For me this is a redundant statement, but I noted that you acknowledged it and i was happy about that. Yes, He loves you, and me, and all of us, whether we are afflicted with bipolar disease, cancer, diabetes, depression, and anything else. Why? Because He looks into the heart and soul of mankind, behind the flesh. Does that mean that He doesn't care about our flesh? Surely not. He cares very much for us, body and soul. You know how the bible says that G-d loves us even more than the birds of the air, and how He takes the time to clothe them in beautiful feathers and feed them, so how much more will He do for us. That's one of my favorite verses, because it shows the very character of our Creator. He even loves the little birdies.. those same little birdies that wake us up in the darkness of morning, poop all over our car windows, steal our vegetables from the garden, and dive bomb us when we're out taking a walk. lol Yes, those birdies. He loves them. (I love them too!) Well, He loves them because He understands their nature, just as He loves us because He can understand ours. We have a sin nature, you and I. We were born into sin, because of the first sins of mankind. So even when we mess up, G-d doesn't abandon us. No no, He loves us in spite of it. He loves us so much that He came down and died for us! Wow... double wow! That's more wow than all of the wow for your deep suffering.
His sacrifice of atonement for your sins and mine, was enough to take away every sin that we commit. As long as we love Him with our whole heart, we can continue to come back to Him daily and say "Oh Father, I have just had the worst day. You saw what I did. Why did I do that? I just don't kow why I keep falling and failing but I know you understand me. Please forgive me again, and help me to become stronger in my faith. I love you and I love what you did for me. I pray this in Jesus name, Amen."
So don't give up on yourself, because G-d hasn't. He LOVES you and He wants a deeper relationship with you. The key to that is for you to start reaching back to Him, in the knowledge that He loves you ENOUGH to forgive you, when you come before Him in sincerity. Not just once, at the time of your first prayer, but every day, hun. Every single day.
Now, on to the other issue of a church. You like to be casual. Have you tried any non-denominational churches? There are many that are really good. If you want to PM me, and tell me the city you live in, I can send you a list of several for you to try out. When it comes to churches, the most important thing is that they teach biblical truths. If they teach from G-d's word, without straying, then they're a good church. That goes for any denomination.
About your husband...
My opinion of that is this:
If you make G-d your first focus, and being a loving, compassionate wife, your second focus, the Holy Spirit will reach your husband.

Spend more time joyfully being a loving wife, and less time being a worrying wife. G-d's word says that we are not to fear, and when you think about it, when has fear ever changed a relationship for the positive?
If you ever want to talk, please feel free to send me a Pm any time.
