Floaters ,neck

Hello to everyone!
I am 23 years old.First of all ,sorry for my english, iam not a native English speaker.
I had an eye allergy before ~14 years that lasted 2 years or more. However it was cured with the aid of homeopathy! optalmologists still find allergy traces-signs on my eyes but i have no sympoms or any other allergy.
Moreover i had eye floaters since i remember my self at the left eye mainly.They were really anoying but i am used to it now..
I feel the last year tightness above my adams apple and i cant afford to wear tight clothes up there.However i dont feel it always. Sometimes this feeling is very annoying...
Here are several things about me:

-Since i was a kid , i was introvert ,detached . Couldnt cope/play with other kids/people
-i was feeling fear
-feeling depressed ,feeling like waste and i was too weak/unable to do anything .Energy levels to 0
-got SERIOUS depression
-got anxiety
-feeling waste,lonely
-at my 17 started to try really hard at all costs.Started to do extremely rude actions.Accomplished many things!
-couldnt have eye contact feeling pain in the eyes
-feeling heavy head and every day seadaches for 4 years

The depression etc belongs to the past.
At my 18-19 i started many sport activities.. Cycling daily long distance, gym,hiking,swimming.I liked them and i was good!
My main interest almost for many years was computer science as i couldnt do anything else with success no matter how hard i tried, i had read tons of books , did many projects ,professional applications for companies ,websites....

-my most serious problem was Derealization/depersonalization i was HORRIBLE.
-i sleep late at nights 3-6 am although i love sun and morning.
-i cant easily concertrate. i am too slow sometimes at my job.Looking too much useless details..

Now, i think it is time to start giving my self attention again. I was too tired from the exhausting things i did to overcome many of my problems... (20 doctors, mentalists,etc..., meditation)

Since i started my last relationship 1,5 years ago i stopped almost all physical exersice:( She hates even walking which i enjoyed now i feel strange. She thinks that it is pointless... and gets angry. Also she is 60 kilos overweight! Wasnt that much when i met her. She has large sugar intace daily and doesnt want to do anything about this.
So, to sum up i feel that it is time to change my self. One difficulty is that something holds me back.Something makes me to do always something and not think about me! Like living mechanicaly. I cant manage my time, and never follow plans,or agenda! If i do it i feel so much stresed that my mind doesnt function!
I sleep only when i cant stand awake.Practicaly i am struggling some way my self to not think things that matter! (maybe that is the reason i feel that in my neck/throat).

Sorry for my long post... and thank you for reading!
I am open to any reccomendations!

P.S also i would like to add that i have some nodules at my thyroid but i think that the big one got smaller as it isnt so easily visible as it was when i did exams.
