I faced a situation like this, I broke my collarbone and it changed my lifestyle to 180. Couldn't go to gym, couldn't do some sports, and affected me mentally to a whole new level. At least that's what I thought. I had a gf at that time. She helped me tremendously. But the hard work it was still on my side.
From how I saw it and what I decided, you have two options:
1. You keep yourself tough mentally, recognize that one thing from your fundamentals is missing, but that's more about how you view it, and not a real issue.
2. Let it affect you and from that point, it's all going down.
Another situation is acnee. I had acnee since I was 14 to 21. On and off. In the summer it dissapeared. That means 3-4 max 5 months. Rest of the year I had my face red, somethimes big pimples, white heads, many evenings with blood on my face because I tried to get rid of them. Now I have some scars. But still, I had girlfriends, I had sex and started talking with girls. It's easier now since I have my skin clear? Yeah, it is. But I take pride in the fact that my acnee didn't stop me to do what I wanted to do.
I suggest to take more responsability in whatever you're going through and make the smartest decision for you to resolve your issue, not just have it and live with it.
You don't want to let it to affect you. You're the same even if something's missing. It's just gonna be tougher. Everybody can feel strong if things are good. The real challenge is to be strong when things are not good.
What I did in my situations was to keep strong as much as possible, but I felt like sometime I could just broke down. And at one point I did. Too bad for me. It's easier to keep strong than to recover from it. The game can be affected.
I conclusion, when things go hard, I recommend just to man the fuck up. That doesn't mean to not talk with somebody, or keep friends/family/gf or anybody closer, it could be a bonding moment, but the power must come from yourself, from your spirit, to say like that.
When life is hard, you must be HARDER.
