It's okay to avoid a potentially bad situation, object or person sometimes to reduce stress but, also it's good to sometimes force yourself to try to overcome your fears. I run into this sometimes when walking back home from the store that's down the street from me. I'll get close to home and there'll be a long way and a short way to continue and the short way for some silly reason, I associate with bad memories and am tempted to just go the other way then, the braver part of me says inside "Face your fears" and that helps me to go the shorter route even if I don't really want to but, when I do it shows me that I can overcome my obstacles if I just try and not give up. Sometimes you have to train yourself to face some things. It's good to start off slow and steady and gradually build up to overcoming greater things. I hope that this helps.
