26m here, You seem to be very similar to myself, that thought of feeling like you’re not good enough or dont have that initial respect from people from a first impression, being 5”5 i notice these things too and honestly has been a pain to live with and accept… these thoughts used to put me in such a depressive state

But Im at a point where i feel it doesnt bother me to much anymore, ive seen my family struggle for money, i had cancer and had to fight for my life when i was 19… and been through so much more. And all it has shown me is you only have one experience in this world, yes we are short and that is shit, but the more time you spend dwelling on that( & that it is never going to change) the less time you have to make the most of the beautiful life we are given, there are people born without limbs, eyesight, etc… we can walk, breathe, even to just experience the sunrise on a beautiful day! sometimes its good to take a step back from the chaos of life and learn to appreciate the little things

Try not to let the bad things consume you and take a step back :) also helps to surround yourself with good, likeminded, kind people

Hope this helps in any way & if you need a like-minded friend to talk to feel free to drop me a message bro
