Depressed about feeling alone.

I didn't really know where to post this but seeing as how I've been feeling pretty depressed about it and it keeps coming up in my mind I figured here was a good spot and id like to at least get it off my chest, regardless of how common a problem it might be so here goes nothing.
Its been a few years since I've been in a relationship and only had like 1 brief fling since. It just seems like no one seems to harbor any feelings for me other than friendship (family obviously excluded because that's not the kind of feelings I'm talking about, I know they care about me as a brother, son, cousin, nephew and so on) I have just been feeling like love is lost to me and I may not say or show anything outwardly but I just feel so Lonely and by myself. I try to be polite, I have a long fuse of a temper and the last time I went off on anyone was back in like 2008 or 09 and even then I had good reason and it wasn't physical. I don't like to yell at people and i keep my cool, I'm polite to everyone regardless of race, gender, religion, age, or sexual orientation. I would like to think that I'm a good person all around but apparently its not enough. I'm really tired of being alone whenever I am home, it just feels so empty anymore and its depressing. I don't know what to do about it at this point anymore and just feel like giving up on having hope, I've held onto hope for so long that its slipping through my fingers and deteriorating.

Anyways for anyone who has actually bothered to read all this, thanks. I know this might be a fairly common thing for people to go through, but I'm in my late 20's almost 30 and the Depression of the thot about being alone is real enough for me. Sorry if all this sounds cliche to anyone but there you go. Tweet
