I want you to know you aren't alone, we on this sub know it can get pretty tough out there, life isn't easy, especially for us, but whatever happens, never, ever give up on yourself. My advice is this, try to challenge yourself everyday to improve and be a better version, one step at a time, and, please, do a favor to yourself, stop comparing your life to others, I did this mistake for years and it was horrible, try to compare you today only with your old self, always remembering your victories, even the small ones. For instance, maybe a year ago you were afraid of going to the gym, then you made progress and achieved something that your old self didn't have the courage to do. ALWAYS value those accomplishments, this will grow more confidence with time, and this is the key for everything, my friend, confidence.
