I’m the same. I only look in the mirror when necessary, if I’m honest. I used to be the opposite, and look in the mirror excessively, which led to even more mental destruction and turmoil.
Just to turn this around for a moment, and I’m very sorry that you too don’t like your appearance, maybe not constantly looking in the mirror (other than when you have to) isn’t so bad. It stops you obsessing, analysing, and distracts you from your appearance, in order to live outside yourself. Sometimes avoiding the trigger is healthy.
Not looking at your own appearance so much allows time to do much more important things. Absorb yourself in these things, as much as possible, and put your own worries to the back. Focus on showing your kind, warm and gentle personality to others, and lend them an ear. That helped me a great deal. That’s what friends really want from you, and you already have a boyfriend who clearly wants and cares for you. He’s no doubt proud. You will then get a respect and admiration for yourself that comes from the inside, then that usually extends to liking the outward appearance. It’s perseverance, patience and hard work, but it’s do-able. The dislike of the outside is very rarely related to what you actually look like.
If there is a genuine problem (as I have physical scarring), remember that the outside fades for everyone. All you need to worry about is cultivating your soul, to be the best person you can, as I’m sure you are doing. Build some self-worth not related to how you look. It changes over time anyway, uncontrollably, and your self-esteem must not change with it. Build yourself a strong base outside of this.
Even if people don’t like after you’ve tried your best, that’s their problem. Why waste your life second-guessing them and allowing them to dictate? I’ve learnt the hard way that they’d never do it for you. You have as much right as anyone to get enjoyment out of life. Don’t live your life according to others opinions. If they’ve judged you badly, they’ve already highlighted one of their clear failings, which is far worse than superficial appearance. And also, no one is that interested, they’ve all got their own issues, and are usually focused on them. If they bully you, it’s usually related to one of these issues, that they are failung to cope with internally themselves, so take no notice. It’s not based on you at all.
I think you are unwittingly giving off the vibe of disliking yourself to others, too, which causes them to react in a negative way often, even though it shouldn’t. They don’t always know how to react. They become unsure of themselves in the face of it. Fake confidence and assertiveness for a while, and see how they respond.
Also, not taking so many ‘selfies’ isn’t a bad thing. The people who do it excessively are often those with low self-esteem and an unhealthy addiction. Actually live your life, taking photos isn’t necessary, it’s the memories you create in your heart and the happiness the events bring that is important.
Best of luck with this.
Take care.
