I agree with Sprawling. Years ago I thought I was hopeless because I was single and never had a girlfriend. I thought my excessive sweating would gross out all girls and because of that, I didn't bother making a real effort to find someone.
Fast forward a few years and I worked on my self-esteem and confidence and before I knew it, I found a loving young woman and we've been together for close to 3 years now (I'm 33 now). I do sweat around her but once I explained it to her the first time (she remarked my hands were sweaty when we held hands, and I told her it's a medical condition), my sweating, which involves full-body sweating, hasn't stopped her from falling in love with me and we're talking about marriage too.
She understands it's a personal issue for me and does her best to support me, and has never made a big deal about it. While there have been times I get so sweaty around her (including when intimate), she's ok just ignoring it or giving me time to cool/dry off. Honestly the only times it's been an issue is when I made it an issue and when I don't make it an issue I feel so comfortable around her.
My advice is to find ways to build your confidence and self-esteem; that's what makes you attractive to other people, so they see past your sweat. I'm sure you can find someone without HH that will love and accept you. It may just take time, but there are people out there without HH or any prior knowledge of it, who is the right one for you. Trust me!
