Re: depression.. I think
May i suggest a vacation or moving? Sometimes big life changing events will open your mind or expand your options.
Do you have hobbies? Consider building on them with more focus while cutting the fat out of your life that isnt positive. Cut it off for a week and see how you feel. Think about the pros and cons and build on all of it by introducing things back into your life. Sometimes by starving yourself of life situations work just like eating. When you cut out meat for a week and eat more veggies you will have a hard time dealing with the routine but normally by the end of the week you will feel more focused and full of energy. Then when you start to introduce meat again into your diet with something small like fish you will see how it effects you. Dont go for a burger or steak right away or else all that work would just goto waste. So when you look at your life and cutting out going out--its not just about being social but spending the appropreate time by yourself and seeing what makes you happy like a road trip, a hobby or meeting new people who inspire you. Sometimes just meeting people isnt going to cut it. Sometimes you need interesting people to help motivate you to grow positively. Give yourself worth, a perspective and openess to making mistakes so you can grow. Change doesnt happen over night. You have to be open to changes and accepting them if you want to reflect a positive change on your life.
I have more i want to say but honestly the above is a really good start
Every moment counts, get out of your head and enjoy it.
