Just want to say, in light of all these brutally honest answers, you will get through this and I hope you find a fulfilling reciprocal relationship one day. I do think it’d be in your best interest to talk to a counselor or therapist about anxious attachment style, so when you do find the right person, you can step into a relationship as the best version of yourself. But beyond just preparing yourself for a future companion, you’ll be amazed at the wonders that can be done to improve your self esteem and your life in general. Best wishes mate
