I'm starting to get depressed while trying to conceive how can I stop?

This is going to be a little long I apologize. But I have been trying for 14 months and I'm still waiting this month too see if my period will show up or not and if it doesn't I'm going to test in a week. Every time I see a positive test or baby bumps anything I get depressed and start thinking about when will my time come. My s.o refuses to see a specialist because he thinks it's just going to put more stress on me  and he's more calm about trying to conceive because he always tells me don't worry about it babe it will happen when the time comes. He just doesn't understand what if it will never come and that we have to seek help. He's just so relaxed about it and positive and I'm not so its hard for him to really understand. I'm in love with someone who I haven't met yet💔😔 it's hard ttc and I'm trying so hard to just forget about it, live my life, and wait till my future son or daughter comes one day. I'm super nervous this month to test its like I want to test but then I don't and if I get a negative or my period I do not want too get depressed AGAIN but it's hard
