I'm really sorry you're going through this and feeling so down, BSH.

Four months is still early into the healing process. The soft tissue, muscles / tendons/ ligaments around the hip take time to fully recover. The groin pain may be from weak muscles trying to support the joint. Also, you may be favoring, or compensating in protection of your right leg and straining muscles, leading to discomfort or pain.
Hopefully you can hang in there and learn more through your appointment next week, receiving some reassurance and advice on how to resolve the issue without unnecessary and painful therapy sessions.
I am sorry for the dialogue that transpired between you, your friend and husband. I understand it was hurtful, leaving you feeling defeated. It's difficult to hear unsupportive words from those you love as you're struggling with your recovery. I am sure they didn't mean to hurt you. Please understand that their words, do not define your future. Recovery is unique to each of us and set-backs, or stalls along the way DO NOT mean you won't improve. Don't let their doubt become your truth. You're right, "words are powerful" so speak your own words to yourself and don't let their's cloud your mind with negativity and color your mood. Kindly express to your husband that you prefer he only speak encouraging words, to you, and in front of you, until you're feeling stronger and enjoying steady progress.
You may be healing more slowly than you hoped for, but that doesn't mean that progress isn't happening. Each step along the way, no matter how small is a victory and worth celebrating. This recovery biz can be tough, but you are not defeated and still have time to heal more than you think. Hold onto that!
May today be a peaceful one for you! Hugs
