Struggling Lately

Been through a few ups and downs the past few weeks. Not entirely sure what is going on with me. It's not a matter of season and nothing major is happening that could be causing any stress or such. All I know for sure is that I feel like it's a struggle to just get through each day sometimes.
   There is nobody I can really talk to about how I am feeling because there is no one thing or any understandable reason for feeling this way. I don't think anyone could understand how or why I'm at this point and honestly don't think they'd care or understand the little annoyances...... especially when they have bigger problems themselves. It's all just very exhausting for me.
The little things:
1) Finances - too little coming in and too much going out, and that's just on the basics. Not sure I'll even have money to eat this next month.
2) Lack of Vitamin B12 - forgot to get my shot this past month and I'm really feeling the lack, it causes tiredness. My body can not absorb it through food or pills.
3) Internal conflicts over past stuff - Parts of me still have trouble dealing with feelings of abandonment and rejection over past events in my life. Even though I know there is nothing that can change the past and there is little to no hope for the future being any brighter, some parts still hope that things will change.
4) Spiritual Crisis - going backward spiritually due to conflict over believes and desire to love, regardless of any conflict. Haven't studied doctrine in awhile because I just don't want to turn out to be an emotionless git like some people I see. It doesn't mean I've given up my beliefs, just that I've hit a wall I can't seem to climb over or go around.
5) Loneliness - Nobody to really talk to. Missing my girls, miss seeing my grand-kids, no "social" life. No idea what to say when someone asks "How are you doing?" because I don't think they really care and I don't want to seem ungrateful for anything. I do NOT want a relationship with anyone anytime soon but I still wouldn't mind feeling wanted/care for.

It's not like life here isn't good. I've been enjoying working the garden and helping mom. I can usually occupy my time alone with DVDs and FB, but sometimes I just get to thinking too much. I am more relaxed here and enjoy going for a walk now and then but have been limited by weather and health. I use to enjoy library time but lately it seems like nothing wants to work right at library. Mostly, there is no real reason I should be feeling so down!
