Depression. Makes my condition to worse.

You want your friends to be with you but they seem to be moving on in life, it seems you are stressed, upset and feel left out and because of this you fear losing everything in life. I can understand it is a difficult situation. There are certain situations in life which are in our hand and certain which are out of our control. You wanting your friends to be with you is reasonable but you cannot control them, it is their choice not in your control, similarly you have choice to be with certain people. Try to figure out your interests and find like minded people. Sometimes trying to fitting in is difficult, make your own path. It will be difficult but not impossible, they moving away from you doesn't mean end of the world, you don't become unlovable, but may be certain behaviors you need to chance, you can very well tolerate the temporary rejection or isolation. Try to figure out those behaviors that need to change.

Consult a Clinical Psychologist for a detailed evaluation and treatment plan for the above mentioned problems.
