Confused, Ive never been like this before...(long sorry)

[Bella xx]

I was with my latest boyfriend for a good four or five months. We were going great and he told me he loved me everyday (I thought we were too young for real love but I figured adolesent love cant be that different haha). But then when the school holidays started he started becoming a real jerk, then last Thursday he dumped me via text message...that hurt me but it gets worse. I then found out yesterday that he got himself a new girlfriend on Saturday, less than 48 hours after he'd dumped me.
But what im confused about is that now I have this feeling of not wanting to be alone anymore. I keep crying a night because im not good enough for any guy. Now I know im only 15 so dont give me all that, "You're still young, you'll meet someone when you get older" bs, because I cant help it, I really wish I knew why I feel like this but I dont...
I just feel so lonely and i dont know why. Ive always been really independant and havent really needed anybody...now I feel as if all I need is a boyfriend and Ill be happy again, somewhere inside me I know that's not true but I just cant convince myself of that fact...
I should probably mention that there is a chemical imbalance in my brain that will eventually make depression inevitable, so I will begin to show symptoms, just noone knows when. Could this be a symptom of it though???
Im sorry this is so long, but thank you for reading it, and thank you in advance for any feedback...

I'm not a psychological professional, so I'm not going to comment on the "inevitability" of depression. I will, however, comment on how you're feeling at the moment. That is completely NORMAL. I mean, before you met your boyfriend, you were independent. After you met him, you began to form a special relationship with him. You both felt that you were needed, on some level. Then, without any real explanation, he broke up with you and started dating someone 48 hours later. If I were in your position, I would be thinking, "What does she have that I don't?" and "What could I have done differently?" Suddenly, you go from being needed by someone to the complete opposite - you feel disposable - and that's a crappy feeling! It's going to take some time to work through those negative emotions, and to realize that you didn't do anything wrong. It's also going to take some time to realize that this won't happen with all of your relationships - with maturity and experience, you'll begin to find men who are better suited as partners. Your ex-boyfriend clearly wanted to be with this other girl, and that's HIS problem, not yours. It doesn't say anything about you being inadequate. Rather, it shows that he doesn't know what he wants from relationships right now, hence the jumping from one supposedly "committed" relationship to another in a short period of time.

As Robin said, we're not professionals so I'm also going to not comment on the inevitability of depression either. However, she's right in saying that what you're feeling is normal. Before him, you were an independent person. You didn't need anyone to get by but once you began dating, you build a special bond with that person. It's normal to feel that loneliness after the break up.

What he did was wrong; he dumped you and two days later had a new girlfriend. I guess we know what happened during that short time. It's not fair to you. But, you need to keep beating into your head that you DON'T need anyone in your life to be happy. Our happiness solely depends on us. We could date someone, and be completely unhappy with that which will only cause more problems for the relationship, especially if you really like them. You wouldn't want that to happen. I think what's best for you is to remain single for a while, and learn to be happy again. You can't be happy in a relationship until you're happy with yourself.

It's understandable that you're feeling upset and lonely. When we lose somebody close to us, those feelings definitely happen. No, I don't think trying to get him back would be a good idea. Instead, try to focus this time on yourself. Are there any girl friends you can hang out with? How about a manicure or some self-pampering? Don't take his actions to you as a reflection of your character. You're still you and it's his problem for not seeing through to it. Time can really help with breakups, so try to spend this time with friends and taking care of yourself.
