Why am I so apathetic towards everything?

Try getting out more. Staying at home , doing nothing but watching movies and playing video games are making you depressed. You need fresh air and more physical activity. Try calling a friend , or connecting with them over fb and making plans to hangout. Practice skateboarding , or go to the gym. Find something that makes you happy and tht u enjoy doing and stick with it. Meet new people! And Put yourself out there! Call up your girlfriend and take her out to dinner! Don't waste your time at home doing pointless things. You'll regret it. Trust me. Live your life!!! And have fun!
