Feeling down

Hi everyone, just lately I've been feeling down because everyone around me is either pregnant or has just had a baby, I'm so ready to be pregnant again! I'm trying to keep hopeful and tell myself our time will come, so I take my vitamins and try to keep my weight down by eating little and often, has anyone got any other advice other than going to doctors? We are trying the natural way for as long as we can x thanks in advance for any advice given x
