I'm DONE!!

I have been TTC for over 7 months and NOTHING has worked! I'm so frustrated with this process!! I'm a healthy almost 26 year old, no major or minor illnesses , no surgeries NOTHING! I know this had nothing to do with it but I don't understand how this process can be so damn hard! I hate to keep trying and at the end all I get is negative test! I don't know what else to go! I'm beyond frustrated!
