I feel depressed & lonely. I need help!

I am losing out on friends and I don't have proper communication at home. My close friends are distancing themselves from me and I get the feeling that they only keep in touch when there's some work involved. I'm a musician and I'm supposed to bring joy and merriment to others lives and here I am, seeking for advice to bring some positivity and happiness in my life. I am aware of my ill habits. I am definitely self centered and I have difficulty prioritizing tasks at hand. I was a reckless person during my college days and have hurt many girls feelings. I used to be arrogant as well, but I have worked on that aspect of my personality and due respect goes to my musical riyaaz that brings a lot of introspection. I know I am not exactly the most handsome guy or witty bloke and I don't keep myself very updated with the world because music and daily practice is my world right now! All I want right now is to be at least liked by people around me and I need help!
