of course do what you have to do to be comfortable with yourself. i used to have short hair, like buzz cut style short hair. didnt like that, so i decided to grow my hair out. during the stage of growing my hair, it looked...funny but i waited and waited until it was long enough where i can put it where i want. go to the gym (rich from me cos i dont) but general exercise will make you feel and look better
Do whatever you feel necessary to make you feelm ore comfortable in your own skin, but honestly as you get older you'll realise you worried far too much and just learn to accept how you look x)
I think this could be a stage we've all been through, of course when I felt like this I did try and do things differently to make myself feel and "look" better but eventually I just couldn't be bothered and it was too much effort and the constant self questioning was getting a bit boring so eventually I just stopped and it didn't do me any harm. Also now that I'm older I just look back and laugh at the things I tried to do because its so silly.
The beauty of Islam is that there is only one sisterhood under the veil. The Burqa offers complete freedom from all the so called western freedom and tolerance and a woman can be judged purely on her actions and words.
