Hi feralava,
Perhaps you just need to find a different purpose for your life? A positive focus, a passion, something constructive that can benefit other people or even the animals, somehow. I mean, that's meaning isn't it? Proper purpose.
You're 27, still at an age of self discovery and growing. What you're thinking & feeling is not uncommon, at all. Just keep an open mind and not believe you have cracked the ultimate questions about this entire universe being meaningless. Keep that question open, please. We don't know everything. Let go and don't worry about men.
Also, a warm welcome to Psych Central.
