I am a little unclear how posting artwork on Deviant Art is your way of asking for help. Please clarify. That comment that was left for you was definitely good counsel. Our thoughts and behaviors are directly linked to our emotions (well the reuptake process of neurotransmitters...but anyway). Here is a brief clinical psychoeducational course:
Work on identifying rational and irrational thoughts, and then remove irrational. Rational: I haven't made any friends. I am feeling depressed. Irrational: I haven't made any friends because "I'm a loser and my life sucks."
--The reality is, it is hard (unless you live in a college dorm) to make friends when you don't leave your house and put yourself out into the community.
Thought Reframing. Original thought: I'm not in a relationship; I'm a horrible person. No one wants to date me or be my friend. Reframed thought: I'm definitely going through a slump now. Everyone has periods where they feel like that. This is a good time to learn to appreciate myself and if someone else sees my value, good for them, if not I will learn to enjoy my own company.
Stop Catastrophizing. Example: Everyone hates me. Everything is awful. I don't deserve any friends. -- Stray away from extreme thoughts; that "all or nothing" mentality.
Thought Stopping. Learn to recognize and quickly stop negative thoughts that impact your overall outlook on life; out of sight-out of mind.
Behaviors:
Start exercising - Exercise boosts mood, increases production of Serotonin and Dopamine. It also boosts self confidence. It gets you outside so you get some Vitamin D.
Start eating well - When we get depressed we tend to gravitate toward the salty foods, or sugary snacks and high fats. Cut those out of your diet. Your brain needs well balanced nutrients. It will create a cycle of poor energy/lethargy.
Force yourself to talk to new people - What's the worst that can happen? If they reject you, you don't have to reject you. That's on them.
Get outside! - The world doesn't revolve around us, and definitely not our room.
Force yourself to smile more - People who smile are found to be smarter, friendlier, and more attractive. If you don't feel like smiling, just do it. Practice smiling in the mirror. The more we smile, the better we feel.
Don't try to illicit sympathy - It's ok to have a pity party once in awhile...just don't make yourself a permanent party goer. People gravitate toward confidence. Work to act as if you are happy. The cliche saying goes, "Fake it till you make it." Also, people who have a "I'm a loser" sign over there head may attract selfish people who wish to take advantage of it.
There's a good beginning. Good luck! You get out of life what you put into it.
