Dear all , i wish if u can help me or tell me whats wrong or what is my condition's diagnosis.

i moved before a year from my house "seperate" to an apartment which appeared to be unfortunately "noisy". Although i was tensed before discovering how noisy it was, but after hectic three months i had an adjustment disorder" i guess" . i heard there are no treatments but i used my family and friends' support. i lost lots of weight "12 KG's" and i smoked excessively and i was obsseses by the noisy apartment. i couldnt move the idea from my head even when i was travelling away from home. i kept running from home and hated the idea of spending time or watching TV in it. actually i still do. later last year i gained some of my weight and decreased my smoking but im still obssesed by the apartment and most of the time im thinking of it , negatively of course. my sleeping is always disrupted by my rude neighbours . i approached them several times but they didnt cooperate. the problem is im afraid to move and to face the same hectic noisy situation again, and to regret moving from my apartment which im kind off getting used to . This is my on going suffering , but returning to the past i can tell similar situations . when i changed my work to a night shift work i had the same problems '" depressed i guess , losing weight etc... " but the moment i quit i got better ! . i have the same condition when i want to take a major step in life like getting married , changing jobs... sometimes the symptoms start before i engage in the activity " when i sign my new job contract or when i date several times and START to think about getting married. i guess i suffer from tension a lot , and by the way i suffer since my childhood from UNILATERAL Hearing .
Please help
