@KevinMao133 you posted this in the love dating and relationships section.
You posted conflicting statements, saying the lack of attention is affecting you, implied you want a partner, then stubbornly refuse to improve yourself or your attitude in order to get a partner. I will offer some basic advice to try to help you.
You don’t have to be fit or perfect looking to find a partner. You do have to have a healthy attitude if you want a partner. There are ugly couples, fat couples, skinny couples, beautiful couples, so looks is not 100% of everything.
Looking through your post history here is a lot of negativity and bitterness. Those two characteristics will repel any well adjusted romantic interest, and I can confidently say that based on real world experience.
Women (and men) can pick up on that type of emotion (negative attitudes) and it is a turn off to everyone except unhealthy partner options.
If you sincerely want to find a partner, you need to work on yourself and your attitude.
If you do the work to improve your outlook and attitude you have a much better chance to find what you are looking for.
I have been married, in long term relationships, and dated enough to know that if you want a quality partner, you HAVE to be a quality partner. You have to be in a good headspace and have a healthy perspective to achieve any real dating success.
Wanting a partner out of sheer loneliness, and not doing any real work on yourself will get you nothing or a toxic partner at best. You need to respect and love yourself before you can hope to truly love someone else.
It’s like needing money and wishing you could be rich, wealthy, or win the lottery. You have to work for the money or buy a lottery ticket. If you are just waiting for a miracle without being proactive, you will wait forever.
The path you are currently on is not taking you where you want to go in life. You will need to change direction and find a new path if you seriously hope to find a partner.
That might mean getting therapy, reading lots of self help info, focusing on yourself and your faults, or exercising to get in better shape physically. If you are not willing to do some or any of those things, you will only have yourself to blame.
