Don't strive for perfection. If you were perfect you'd have nothing to aim or reach for. Life would be boring. Just keep trying to be your best self, that's perfect.
Love yourself. Appreciate all that you do/try to do for yourself. Find things you love about yourself and if there's stuff you wanna change, change it. If you can't change it grow to love it or at least tolerate it. Loving yourself will help you out a lot.
Don't be afraid to try something new or step outside. Something good could happen, something bad could happen. Just prepare yourself best you can for the bad stuff.
Keep going. Keep your eyes ahead and tough out that storm. Nothing will be perfect but things will get better. If they don't get better you will get better because after bleeding and scaring, putting yourself together countless times, you'll grow tougher and get thicker skin.
Please don't be afraid to talk to people or get help. Life is arduous as it is and you can't go about the transverse alone without help. If you have nobody, I'm here and willing to help you however I can.
Take care, and happy holidays. Be good to your body; it's the only one you have.
