Dating seems rigged against average guys. Thinking about giving up

Pretty much the title. I'm 26. Been single all year. Trying to put myself out there. No luck. Dating apps are a living hell. Out of the dozen I use I only landed two dates and both girls never responded after. I go to bars and clubs every weekend and it's become torture. Its hard to enjoy my time out when I look around and see people just living and I can't help but wonder what is so wrong with me. I'm a good looking guy. I dress better than I used to. The past few times I try to approach someone they look at me like I'm a monster. But apparently I can't just approach anyone. I have to wait for eye contact and a dozen other signals before I can even think of making any move. I have to say everything 100% correctly without a shred of nervousness. Anyone I see that catches my eye I'm told to ignore. On top of all that I'm also supposed to have a fantastic career and tons of friends and social circles. Its so intricate and complicated just to ask a girl out I honestly can't grasp how everyone else does it. The one and only girlfriend I've had feels like it was just a freak chance. I have 2 friends who I never get to see and a roommate who won't go out. I can't find joy in anything anymore I just feel hollow. I feel so isolated I'm just longing for any connection. I'm at the point where I'm trying to sever the need for companionship or friendship of any kind. I don't expect anyone to understand or care I just have to vent. I just want to stop breathing already.
