So tired of being sick and tired!!

Well it's been a while since I have posted here and for that I'm sorry...so much is going on in my life good and bad! I have finally met the man of my dreams! Someone who loves me for who I am and understands all my problems and issues and doesn't judge me or get frustrated with me! Someone who loves me like my dad loved my mom! I never thought it possible to find that kind of love and I have! But now that I have, my health issues are all consuming!! I'm constantly thinking up some horrible disease that I must have because the docs can't find anything wrong but I have all these crazy symptoms!! I tell my fianc all the time that he's not gonna have me long because I'm gonna die soon! We are getting married next Saturday and I can't even focus on getting things ready for the wedding for focusing on all my crazy health problems!! I feel like I'm gonna break! My daughter barely comes around because she can't stand the negativity!! I don't blame her! I love my kids and my fianc with all my heart but how can I make them happy if I can't even find peace and happiness within myself??!!! I really need prayers!!!
