Any kind of negative emotion is energy-draining. The stronger the emotion you yield to, the more energy you lack. Let me tell you this. I have never had a girlfriend, my social skills kind of suck, I have quite a number of bad habits and generally I feel the way you described. I've been lurking incels for some time because I totally understand where you come from but at the same time I don't identify with your ideology (blackpill, 80/20 rule etc.) I've noticed many users here carry a defeatist attitude and provide no kind of support whatsoever. If you feel depressed and you wish for things to get better, I have to warn you that the tips I will give need to be applied as a long-term solution. Don't expect quick results. Battling depression or any kind of chemical inbalance in your brain is a matter of time.
Firstly, I strongly encourage you to limit visiting this site to a minimum. I know it might be the only place where you feel understood but it only sustains distorted beliefs on life. If you identify with them, please take a moment and reconsider them. Most of the views here are wrong, plain and simple.
Secondly, drastically limit watching porn. Once a week is good enough, but try to fap to your imagination of real-life scenarios. The overuse of porn is, I guess, the reason for such a distorted view on women. You need to wake up to reality and it cannot be found in porn which is, I guess, the only source of your knowledge about sex and stuff. Also, try to limit your time on video games and the internet in general. Video games and the internet are simply speaking, fantasy.
Next thing, check your posture. If you are depressed, chances are that you slouch and don't care about it whatsoever. Straighten your spine and pull your arms backwards to align them with your chest. I can tell you from experience that it gives good results in a short time. Just keep that in mind - learning to have a pernament good posture requires effort and constant check-up. Personally, when I started walking straight and my head up, I felt less likely to be swayed by negative emotions.
Another thing, physical exercise. Gym is the popular one here but I prefer simple half an hour jogging. It puts you in an elevated mood for some time and releases endorphins to limit the effects of depression in long term. Personally, after half a year of regular jogging I feel much much better than before. I still feel negative sometimes but there is definitely a difference in the overall mood.
Next thing is meditation. This is a huge one. It helps you put things in perspective and be more aware of what is going on in your mind as well as become more humble about yourself. Meditation helped me realize a lot of things about myself and a lot of problems which I should have adressed a long time ago. I strongly suggest to check it out. PM me if you need more info, I can give you some useful tips to help you avoid some mistakes I did in my practice.
And generally, try doing things that you can feel proud of. Really. It helps you feel good about yourself. Start small. Clean up your room. Clean up the dishes. Do the thing you postpone all the time. Put your effort in something good. Personally, I started to feel less anxious around people when I had nothing to hide from them. When I started living to my own standards, I felt less self-conscious and more open to another human being.
Finally, if you implement all of these advice, after some time you will start feeling better. Then, I suggest simply going out to people. Start small. Make sure you do it quite regularly. Don't force yourself to go out. Do it only, when you feel inclined to.
That's it. I wish you good luck with your depression and remeber - put someeffort in your life and you will see the results. Just be patient. You can do it. Peace.
