It appears underneath you want so many things, but not willing to go out & get them, hence the low self-esteem, leading you into thinking low of yourself, for not having these things.
The only way to fix that is to start pursuing the things you want, for you'll find out if its worth the effort or not.
Don't look at what others have & wish for it, they show if off because they really don't understand how to enjoy it other than showing-off, & people like you get depressed for not having something that's either in-enjoyable or very over-rated.
Do the things you like, i'm sure you have an opportunity, it'll take away the ridiculousness that your mind is in.
