Fear after ectopic pregnancy

Hi ladies! So great to have this group and talk about this heartbreaking stuff!

So I have had an ectopic pregnancy 2 years ago. I was close to 8 weeks, the foetus had a strong heart beat but unfortunately... it was in the wrong place,as the doctor said. I have been through severe depression after and it took me 2 years to ‘heal’ ( can you ever fully heal from this?). We are trying to conceive now but although I am positive all will be fine I am talking myself down: it will never work with 1 Fallopian tube, I am too old ( 37), it will go wrong again.... how do you beautiful ladies cope with emotions and thoughts like this? Thanks in advance!!
