Begin doing things daily that are important to you whether they make any sense or not.
Are you working out daily? If not, start.
Are you doing creative projects with your free time?

Begin to make yourself into who you want to be and someone you are proud of. Others will see your confidence and treat you accordingly.
When others see a weakness in you, they will offer all of this unwanted advice that you are suffering though.

So do not let yourself appear weak. Fake it till you make it if you have too.

NO, this isn’t not being true to yourself because you are working towards your truth.

The person you are now is getting the advice for a reason. Somehow people are getting vibes that you need advice!
Don’t put those vibes out there.
Be strong, confident, assured and look them in the eye when they say something and let them know you have it ‘under control”.

You are only 24. Give yourself a break while you are at it. But do start conditioning yourself.
Read something inspirational every day. Find what you truly love.

I wish you well!!
