Depressing thoughts

I will try to make this as short as possible
Grab the popcorn- 
I have been with my partner for 7 years- met in high school lost our virginities to each other.
Found out I had endometriosis- and was told that falling pregnant will be difficult for me. 
I'm 22(23 September) he is 21(22january) and all of our friends are engaged and expecting babies who are much younger and have been together less than we have- I have these thoughts that I'm not good enough and scared than I have 2 years that I could attempt for a baby and he won't try because he isn't ready- I don't want to pressure him into it because it's a huge step and very scary to ask that if someone but there is no sign of us moving forward and I don't want to waste my precious time on something that I won't have a future with- it's made me so upset and thinking horrible things- I wrote suicide letters to my family and looked up ways to kill myself- I am genuinely upset so I don't want people being even more mean than I can deal with right now but thank you for information in advance
