I personally do not think that loving yourself is the problem. I see two problems:

1) grossly unrealistic expectations. When you are in a horrible relationship, it might take YEARS to recover (I know that). I do not know how long your horrible relationship lasted, but I see that you wrote "months ago..." as if months ago were a long, long break that should have gotten you back to normal. Months ago means you barely got out. Release the unrealistic expectations - do not expect to be back to normal yet.

2) over-thinking and excessive analysis. But if you do (1), (2) would most likely go away on its own, without any deliberate work.
