Can I conquer the intrusive thoughts in my mind, and live a normal life?

personally had ocd/intrusive thoughts, what the therapists usually say is to try to not enlarge the thoughts and simply put try to find a way to not listen to them, they're just thoughts not your actions you're the one that decides.
thing is you gotta find your way not to care about what you think, remember you can't always run or distract yourself, at some point you are going to be alone. I try to act as if I can't remember anything convincing myself not to bring up memories that make my thoughts, you need to find your own way not to enlarge your thoughts.
and an important thing is to enjoy life, usually anxiety and sadness bring up the intrusive thoughts, just try to enjoy life at all cost anyway you know.

change your diet OP and definitely stop consuming sugar. sugar not only destroys the body but also reeks havoc on the mind.
also stay away from alcohol.

I don’t like the thumbnail. Women don’t have it hard in 1st world society. Also, quit being a bitch, and be homeless, like me! Rent is car insurance, and I meet new people everyday

Intrusive thoughts are your subconscious minds way of screaming at you. What does it want? What do the screams say user?

I already don't eat a lot of sugar, and I don't drink. I could stand to have more vegetables though.

It was the best I could find on Google Images.

Sometimes I can get them to back off for awhile. Then sooner or later, I remember that I'm forgetting something, and they come right back.
Three times, they've crept into my dreams. That makes it ten times worse, it wrecks me for the whole day pretty much.

Assuming you're right, it probably wants me to kill myself.

You dont want to die or else you wouldnt be posting and you would be on your way to either a hospital or a coffin. What you want is to kill the part of yourself that you dont like. Isolate this less desirable version of you in your head and excise it from yourself.

Is it really that easy?

Hell no it's not easy. But you can bet your ass its easier than fighting your own psyche for the rest of your life.

ok user.
i was letting you know what worked for me. at one time i was a train wreck. high anxiety, paranoia and intrusive thoughts but i was a heavy drinker.
i gave up booze and my symptoms greatly decreased. it was like having a new lease on life but i still had some anxiety and intrusive thoughts issues. but not nearly as bad as before. then about 4 years ago i wanted to loose thirty pounds so i severely decreased carb and sugar intake.
no breads or pasta. no soda or cakes and candy and it really helped.
now when i do eat those things my mind races and i cant sleep and i start projecting into the future.
i don't know if any of this will help you user but i wish you good luck.
