@Squirrel Lover I feel your pain. At least it won't take long to grow longer. Unfortunately, I had an experience a few years ago that still has repercussions. For years, I had gone to the same person who trimmed a 1/4 inch off my thin fragile hair that I had babied and nurtured and kept the same length for the past 30 years. Finally It had grown to half way down my back and my husband loved it.
I went in to get my regular trim and my stylist was no longer at the salon. The person who cut my hair lopped off the crown area to 1/4" turned me around in the chair and proceeded to layer the rest. She must have realized at some point what she had done because she left a few straggly ends at the bottom and pushed that hair to the front so I would not realize what she had done. She left it wet, instead of a blow dry which I thought was odd. On my way home, I ran my fingers through my hair and was in shock, it felt like I had no hair due to the thin layers. When I got home, my husband's remark, "what have you done to yourself". Later, I found I couldn't run a comb through the layers, my hair felt rough at the end of the layers.
I try in my life to use every disaster as a learning experience. I've tried thinking...it is only hair...I'm not dying of cancer....it could be worse....good lesson in vanity...this is not your priority in life. But a day doesn't go buy that I don't think about it. I probably won't life long enough to recreate what I so carefully tended to over the years. I have not had it trimmed or even looked at the back of my hair. I know....I just can't.
My lesson is acceptance. I'm at peace, it's just hair, my priority in life is to grow and I am grateful for so much in my life, even this lesson in my better moments. I learn to ride the waves....
