My mind is mixed up

My mind is mixed up! I have many things to say but don't know how to start. I guess it is because my mind is wandered around and around. Too many things in my mind and I want to deal with them all in once. Although I know it's impossible, I can't help it! I am quite mentally tired, but thanks God He talks to me through the Bible and so I can follow His word.
I was struggle with my relationship with a friend, and praise the Lord that He gave me courage to write to this friend and I got her response. Now, thing is settle and hopefully we can build a better relationship afterwards.
I kept thinking about my career plan. Should I get back to work after maternity leave? Should I be a full time mom? Will I miss Elisha's significant stages if I go back to work? Will I regret I give up my career to raise her? Can I balance my life if I work part time? Will it be too risky financially if only one breadwinner in family? Will I lose my productivity if I don't work? Will Elisha get good care if I work? What if I have a second baby?
I don't want to worry because I suppose to rely on God and let Him take care of me! I don't want to worry because I need to set an example to Elisha that we lay our burden to God and we are worry free.
Thanks God that I can share my worry to my friends and their comfort really warm my heart.
