This is just a personal opinion, but from what I can see, you want someone, correct? And you want to feel confident to get out there and meet people but you feel low. Is there a particular reason as to why you feel low about yourself? is your lowness due to low self confidence and low self-esteem, afraid you won't have someone? If that's the case, then work on those two: self-confidence and self-esteem.

By working on these two, i mean, things like learning to love yourself, practising social skills, working on your smile and posture (or does that only apply to girls?), and respecting your own body by immersing yourself in healthy physical activity, or other hobbies. Focus that negative energy elsewhere. The only way to "get out" is to actually "get out" It'll take time though, it won't work overnight, you have to get used to it and get used to feeling good about yourself first. You will find that you'll have a lot to work on for the time being, but slowly the outcome will be great as you take little steps to achieve some confidence and stop feeling so down and pathetic...

Unless there's another reason for your lowness.? Like a past story or something..?
