OP, you are not alone, so many of us feel this way at one time or another.

If your girlfriend left, you are better off. You have been hurt and are looking down. This is a huge turn off to other people, but a necessary stage--to mourn your losses and move on.

Your spirit is telling you you are going in the wrong direction. It is giving you the nudge that this is not how you should spend the rest of your life--take heed and spend some of your free time exploring other options.

When you are feeling "right" again you will attract like minded women--who can be trusted--you just need to be selective.

Your best bets for "feeling" better are...

1. Make sure you are getting good nutrition and sleep. Take a multi vitamin, and don't drink every night. Niacin is good at helping with depression--google it--simple Vitamin B-3, I wouldn't be a day without it. (it is harmless and cheep)

2. Exercise a bit at least 5 days a week till you sweat hard--the effects are wonderful.

3. Volunteer at something you can feel passionate about--you will meet like minded people that way.

4. You are young and single--the world is your oyster, anything is possible.

There are a lot of people out there teaching that what you "tell" yourself, "your story" can harm you or help you. Basic positive thinking, but really is true. The more you tell yourself that you got screwed at your last job, your girlfriend left you and your parents suck, life seems pointless--it makes these things have more power over you.

Imagine that the damage that was done to you (as you perceived it) is like a cut on your arm. Every time you tell yourself your "story" or others...the cut gets deeper.

I can highly recommend "Byron Katie" and "Tony Burroughs"
