Tiredness

I still feel so tired and sometimes even exhausted, will this ever go away, will the meds i'm taking give me my energy back? I'm the type that has always been active with my kids, and now, just to get out of bed seems like a strain, and it's driving me crazy, and I get so depressed when I tell my kids not right now, i'm not feeling well. We went to Disneyland on Sunday, and I pushed myself so much that day that it took me til yesterday to recooperate. This really stinks, Please someone tell me that there is light at the end of the tunnel, and how long before I feel like myself again.
