<human>: Can you condense the text into a few key points?

So I have realized this for a solid year but I seem to be in a weird cycle. All my life I have always committed to things such as internet forums, games, girls, hobbies, clubs, and friends but it seems that after awhile depending on how well I enjoy everything, I seem to quit.

For instance, I've been a member of a club in college and I have busted my ass and became an officer and still working hard. However, I am losing desire to continue. I find myself getting irritated with the people and just the typical bullshit, but this is not where it ends.

My last major girlfriend was 9 months and I just lost all feelings just like my club. We broke up because i was... indifferent. 

A last example would be my DnD group, I was a super committed player and my DM always talked about how I did a good job but recently I could care less. 

It seems I am super interested in things, commit and succeed but then for some reason I lose all drive and switch to something else. As you could imagine this fucks with my mental health a lot because I am constantly rebuilding my identity and everything. I have some bouts of hardcore sadness every few weeks for the past 6 years, recently it has been about 2-4 days of the week I'll feel awful and hate everything including myself. I've never been to a therapist but have considered going.

Anyone have any ideas what the hell is going on, cause I sure do not. 

Thank you for reading this.
<bot>: I have a passion for activities, people, etc, commit myself for a good chunk of time and then burn out and quit. Time period ranges from 6 to 2 years for burn out. Help.
