Very good advice from bonez. I my self always felt depressed from being just that bit shorter. Esp in my early twenties. But when I realised there was a solution, I used that as motivation to work harder and saved up. Now currently doing LL, its not done yet, and I hope its finished by end of this year so I can go and just enjoy life.
Also, whiles leading up to LL, because I became motivated and to work hard and learn to push my self, I actually felt less depressed.
Last thing, I failed to realise this until late in my life, I had alot of toxic people around me. I learnt to just cut them out and tyat really helped me mentally.
