Hi... I will not suggest you to seek Therapy/Counselling to fulfil your loneliness, as it is not meant to replace social/personal relationships or to fulfil one's emotional needs.
Therapy is meant to bring change from within and to help a person better adjust to his own thoughts, emotions, behaviours, and his/her environment.
Your presenting issues (loneliness, low self esteem, high need for affiliation) might be just out of your introversion and more because of this pandemic situation/restrictions.
Lot of people are suffering from similar issues and are gravely effected by the Pandemic. People have lost lives, livelihood, jobs, homes, properties, businesses. We are all finding it difficult to deal with this kind of an environment.
So, that way I do not see your issues as any deviance from the normal. But still there are no prerequisite to seek professional help. You can always consult a Psychologist and address your concerns in a therapeutic setting.
Next Steps
Give yourself some time and seek professional help if you want work upon your presenting issues.
