Tired today!

I'm tired today... Do you ever feel like your constantly battling? Well I do! I've been feeling like so many good things are happening in the Spirit and my heart is really connecting with the Lord lately. Then bamm I feel like I get knocked down or something (not slain in the spirit either) and it is such a battle to get back up and fight. It's like I'll feel refreshed for a couple of days then I'm wiped out for another day. I just have to trust and lean on Him and not on my own understanding. I think I'll just go to bed early and maybe He will give me a dream or something and I'll feel better. Sorry for a downer just had to process this out loud. Ya'll have any encouraging words?
