How do you handle situations that seem too big?

I have brought this question to my own self in the past week. In the last year, I've had big ups and downs. They mostly seem like downs, but I try to keep positive. In a years time, my marriage finally fell apart after 4 years of trying my best. I never dealt with that pain because I knew how my family felt about my marriage. They seemed almost ecstatic, no probably more relieved that it was finally over. Well, because they felt that way I never shared how I really felt about my marriage falling apart. Also in that years time, I met a man who I learned to love with all my heart. This is another reason that I never dealt with issues. He took my mind off of the hurt I felt. I wasn't feeling alone so never had to think about things that were all fixing to come crashing down.
In the middle of the summer, it was brought to me that my office may close down. I still kept positive because I knew that God had everything under control. Since June everything has been going well and business has picked up, until yesterday! It looks as though my office is moving another 15 mins away or even closing. Now, I had orginally had peace about the whole thing because I was told I would still have a job. That might not be the case anymore. This has me very worried.
Back, in September, I lost the man that I loved. We decided to end it for several reasons, even though, we both feel the same for one another. Now this is hard for me to crasp because I don't understand how you long to be with someone, but decide not to be with them. It seems crazy to me! Well, we were friends, until last week. I decided we couldn't move on unless we cut out all contact. This is hard for me. Very hard. I miss him like nothing I've ever missed. My heart longs to be with him, but it can't. And I feel a physical pain.
Now I'm telling you all this for a reason. Through everything in my life it seems as though I have peace about everything. This is not because of me. Its only because of God. I'm not saying any of this because I want pity. That's exactly why I haven't said anything to many people about how I feel. People have come to me and said, " I'm so proud of you for the way you handle the stuff in your life!" Wow! That is something big for someone to hear. Exspecially me.
How do I feel? I feel alone, I feel heartbroken, and honestly, some parts of me doesn't even know how I feel. Why am I saying this? Because I have peace! I know that God is over all things and this too he is over. He has someone prepared for me when the time is right. That person will be more than I ever imagined possible. God had my job under control. I need not to worry! I pray and let the Lord know what my heart's desire is and whatever his answer is is more than I could want for myself. So when you have the world crashing down around, have peace. Know that God is here with you. He is fighting with you and wanting you to come out victorious! Remember, God made all things. He is above all things. So why worry when you have the Master on your side? I have peace and I know everything is gonna be alright! Praise God!
